Is there a standard setting for the microstep jumpers?

What is the “standard” voltage for the ramps? All the reprap stuff says 12-35
Pololu says 8-35 is ok for their board. I am using basic nema 17 steppers, one is from adafruit, the other 4 are from sparkfun. They are the standard 200 steps/rev and the coils ring out to about 33.5 ohms each.
Do most people use 12v because pc power supplies are common or is the higher voltage better. I have been doing some reading about the .707 (rms basically)something something. Darn it I can’t remember if that was amps or voltage now. I think reducing amps reduced torque a little, but heat like twice that.
I noticed the only thing that 11a circuit fed was D8 fet, seems like that is the extruder heater. If my supply can feed 20a, I can just bridge them.
I also read about not feeding more than 12v to the mega…
So is 12v the standard or is 24 or something better?
