Wow, love how this degenerated into a Presta vs Schrader debate

(While we're also somewhat on the spelling debate, the one I use is from Wikipedia, FWIW: http://en.wikipedia.org/wiki/Schrader_valve)

I seem to prefer the ride of my 27" wheeled Varsity to that of my 700c wheeled Trek, but that's probably as much to do with tires and the frames themselves as anything else. Go for what's more convenient for YOU.

FWIW, I've used both Presta and Schrader valves and had no more or less trouble with the actual riding use of either. I will say, however, that the join of valve to tube is much stronger with the Schrader valves than with the Presta. If you're a bit of a clumsy gorilla (like myself), you can rather easily break the valve off of a Presta tube when you go to install a tire. Having this happen once was enough for me to decide that if my wheel can take Schraders, that's what I'll be buying.
