I picked up a Rocky Talkie 5W radio.  Some peculiarities:
All channels are set to narrowband by default.  You can however go through a process to change each (high power) channel to wideband, and the change persists across power cycles. Channel 22 had a CTCSS tone configured out of the box. Its "TX beep" is local only, meaning when the beep's enabled it doesn't transmit the beep.  It is not a roger beep. When setting CTCSS/DCS tones you can only see a slot number, not the frequency itself.  Set your repeater tones with manual in-hand before you head out! The scan feature only offers CO mode, continuing scanning a few seconds after carrier drops. You have to enable repeater channels with a special power-on sequence.  Once enabled, they stay enabled across power cycles. What I like about it:
USB-C charging. Solid feel in hand. Battery life should be great, I haven't tested it. Simple enough for any family member to use. Relatively small size. The clip actually is a set of jaws with teeth for traction, unlike most clips that are a single blade that just presses against the battery with a bottom lip. Honestly I didn't buy this to use it, but I make accessories for HTs and needed this for that purpose.  I thought some of you may benefit from these observations.

I think I'm not breaking rules by posting this here, but happy to be corrected by mods if this self promotion is inappropriate.  I make and sell stands for HTs, for the NanoVNA-H4, and for the tinySA ULTRA spectrum analyzer.  https://blacklodgecreative.etsy.com
I've also designed and printed TPU dust caps for connectors like SMA, type N, SO239/PL259, etc.  They come in handy.
I try to stay up to date with the newest releases 👍

Very likely a screw-up by people who implemented algorithm for particular hardware. I was at this very place some 20 years ago, working on TEA implementation (not related to radio). Used uint instead of int in one place, and it caused a degradation of entropy. Luckily, my mistake was caught in time and never went into production.

There never was. Advances in decryption algorithm design, number theory etc. soon renders many cryptographic techniques obsolete.
The point of most encryption in the public arena is to foil the "casual" radio monitor. i.e. those with scanners, or scanning two way radios. Making the cost, in terms of time and hardware, significantly higher than the value of the intercepted communications deters most people from bothering to try.
I have on order several ARC4 40 bit encryption licenses for my NX-1300 DMR radios. Is it secure? No, but should be good enough to lock out the "casual" monitor when used infrequently and the key switched on a frequent basis when it is used.
Some of my other radios, the NXDN and P25 types, can use a special digital encryption module, which requires a special cable and external hardware key loader. Those modules are expensive. They also have to meet various tests for security. See attached file.
There are also various types of analog scrambling modules too. I've attached a sample for a TK-3170 radio.

On the pricier side but good quality the Wouxun KG-S88G. It’s IP67, it has a screen though it is smaller and it’s superheterodyne. On the cheaper side the Baofeng UV-9G. It is also IP67, smaller screen, not superheterodyne but duel band, more frequencies on RX. It’s cheep enough that if something happens you aren’t breaking the bank. 

I agree jump in and get one, then another. The best radio is the one that’s in the mail and on it’s way 😂

The OLYCOMM repeaters have general use "open" tones and you can read about them here:
https://www.radioofhope.org/oly-comm-volunteers
I listen and sometimes participate on OLYCOMM3 and it's fairly active.  There's a weekly social net on Wednesdays 8:30pm - 9:30pm, and a weekly tech net Wednesdays 6:30pm - 7:30pm.

I put a spare (Diamond) 1/2 wave 2m/70cm mobile antenna on my Chevy Bolt with a hood lip mount and was surprised and happy to get ~1.3 SWR on GMRS as measured by my fars-o-meter 2000.  The way I see it, a mobile antenna with directionality is way better than a rubber ducky antenna inside the car.

I don’t own the 935 but I do have the GMRS PRO, and so far I like it, though I don’t have another radio to compare it to. Programming was easy one I worked through the app. Sounds good, and battery life seems to be good even with the GPS on all day. I did order a KG UV9G pro that should be here tomorrow, then I can see how much I really like the GMRS PRO. 

I have both and for my interests I prefer the KG-935G over the GMRS PRO.  Programming the GMRS PRO was a terrible experience from my mobile (iPhone).  The BTECH would be more useful if it's what all my friends have, but it's not so the location and texting features aren't useful to me.  If you're of the "do everything on mobile and don't touch a desktop/laptop computer" type of person you might like the mobile programming aspect, even if it doesn't work well.
The BTECH claims IP67 water resistance whereas the Wouxun claims IP66.  The bottom of this page pretty well illustrates the difference.
The BTECH comes with a 2,600 mAh battery and the Wouxun comes with a 3,200 mAh battery.  However, you can't draw much conclusion about runtime from this alone.  You may want higher capacity at all costs, or you may prefer lower weight.
The full DTMF keypad on the Wouxun may be more familiar to you if you've used any other radio with common keys, whereas the interface on the BTECH is more different.
The Wouxun can store 199 channels, without memory banks (channel groups) whereas the BTECH only offers 6 banks with 30 channels each.  Your use cases will dictate whether "more channels" or "selectable banks of fewer channels" are a better fit for you.
The BTECH offers integrated USB-C charging but the Wouxun does not.
The Wouxun offers dual receive but the BTECH does not.
The Wouxun offers VFO mode (can tune to a specific frequency) whereas the BTECH does not.
I'm not here to tell you if one's better than the other, but there are some key differences that you can weigh against your goals to make a more informed choice.

Yes, I got my KG-UV9PX this past week and compared it with a friend's KG-UV9GX and the bodies are exactly the same.

I have both coming.  I'm hoping they share a body and just run different firmware.

What applies to ships at sea also applies to vehicles on the ground. Many years ago, after working on vehicle mounted radios for the military, I went to work for the oil industry, and radios aboard a fleet of ships. Well antenna gain issue cropped up often, as many think more gain means more "amplification" of receive signal, not realizing that it is also the radiation pattern impacting signal as BoxCar mentions. Very often, someone would place a 12 dB gain antenna on a small vessel and it had trouble talking to a larger vessel, even when in line of sight and close in distance.
An isotropic antenna would radiate like a sphere, while a 3dB gain antenna may radiate like a doughnut, 6 db gain antenna like a pancake, a 9 dB antenna like a thick tortilla or naan bread, and a 12 dB antenna like an LP record. So, with a 12 dB gain antenna on a small vessel, and a 0-3 dB gain antenna on a large ship, the only reliable communication (due to height differences between vessels) is when the little one is bobbing around and the radiation (transmit for smaller vessel and receive for larger) match up. This is where height and a 0-6dB antenna are much more useful, as they both have transmit and receive patterns that can reach other stations. Power is also an issue, as more power in a more focused radiation pattern can mean more distance. Cars and fixed radio stations are impacted the same way. 
When it comes to wattage and a mobile radio, Part 90 radios in use by public safety, commercial use, and hobby use are often limited to about 50 watts. Motorola, Vertex, Icom, Kenwood, mobiles are often 25/40/50 watts. Attached is a lab kit for Radio over Internet Protocol, with a Motorola XPR4550 UHF 40 watt mobile shown. I used Motorola mobiles for GMRS, with my CDM1550LS+ at 50 watts. GMRS radios usually max out around 50 watts too. Radiation exposure specifications will usually specify 6 foot or so (sometimes less) of separation between people and antennas in the UHF range at 50 watts. 50 watts mobile, with RG-58, and the shorter run in a vehicle than up a high mounted fixed antenna will get you ten to twenty miles, depending on terrain and local conditions. I myself usually run about 10 to 20 watts mobile and have no problem hearing people, hitting repeaters ten miles away, and transmitting back. The radio tops out at 10 watts, my RG-58 cable run is about twelve feet, and I have a decent antenna on the trunk which acts as a good ground plane. If what you have works, then let that itch go to a basestation, or a handheld that can be taken when not in your vehicle. Glad to see someone else get further into this......GMRS has taken off over the past few years for sure.
