Does it really make a difference how many degrees a servo turns?

I noticed a lot of the cheap Chinese servos list them as 180, 210, 270, and 360 degrees. My question is, for a 1/10TH scale or 1/8th scale, which is best? I always buy either the 210 or the 270 ones, because i always assumed the 180 degree wouldn't turn enough, but, am i wrong or is there something I'm really missing (most likely). Does how many degrees they turn really make that much difference?
 
For RC cars, you're probably not going to be using more than the default +/- 60 degrees, do you find yourself setting the endpoints very tight on the high-turn servos? Or are they just stalling at the ends of their travel? The difference is the accuracy you'll get from the remote to the servo's position, not much more than that if you still set the endpoints correctly.
 
Anything past about 120° is useless for steering purposes. As the horn travels around the rotation, it is moving the steering exponentually less the farther it travels from 0°. And by the time it hits 60° from center, it already isn't doing much.

Basically, no it doesn't matter. As long as you can set endpoints with your radio, either via a dual rate knob, or an actual endpoint adjustment.
