Range is really determined by line of site. At 3 feet of the ground, the furthest you can normally communicate is 1.2 miles if you calculate the curvature of the earth. Unless you are doing something like AM radio, which can actually reflect off of the ionosphere, you are more constrained by the height of your antenna than by the power of your transmitter. People have used these 0.5w transmitter radios to communicate at 125 miles, but that involved someone being on a mountain.
GMRS technically allows a higher power on the same frequencies, but once again that doesn't matter much if you don't have line of sight. The big advantage of GMRS is that it can use a repeater. Repeaters can be mounted on tall towers. Which means they can communicate much further. This is why they can make use of the higher power. For unlicensed handheld radios, these are as good as everything else.
