Going back to one of my old experiences when I worked for Motorola years ago...
A small city police department had a failure of their old GE repeater they had been nursing along for many years, so they needed a new one. Budgets were tight, but they insisted on a 100 watt unit. Now, the repeater was naturally on a hill, on a water tank, and was at the highest point in the city, and no more than a mile from the city limits in any direction. They wanted 100 watts. VHF, carrier squelch mind you...and 100 watts.
While they waited for a new repeater, we loaned them a Desktrac (not what you need for public safety, but it'll work in a pinch).
Once on the air, the asst chief said, man, that sounds good. And the range is great, can we just keep that one? Is it 100 watts?
Sure, it's 100 watts.
It was in fact 25 watts..... no one could tell. They later got a new repeater, but we still didn't set it up for 100 watts.
Point is, don't get hung up on wattage, use what works for the situation you need it in.
