Pick the bike that fits you best. You won't ride an uncomfortable bike very long.
Dude I work with rides his "bad-debt bike", a little V-star 250. He's 6'3" and ~240lbs. It actually fits him well & he loves it (likes it so much, he sold his 900 Vulcan!), but especially in his cold-weather riding gear, he does look a bit like a circus clown.
It's an oddball and a half, but I have to mention this: my wife
adores her Hyosung GT250 Comet. (It's a "naked" bike, basically a standard.) Despite the little engine (an air-cooled, 8-valve V-twin that loves to spin), it has plenty of power, and is perfectly capable of running 70-75MPH. It's really wound out on the highway (IIRC, 75 is 9000RPM), but it's clearly built for it...honestly, without a tach, you'd never know it! The Comet GT650 is on the same chassis--unlike most 250's (especially the Rebels), it is not a "mini-bike", it's a normal-sized motorcycle. Note that the GT250
R/GT650
R is very different! Note they did not get EFI until 2010. Liz is tall and the Comet fits her nicely. If you do not have long legs, it will likely not fit you well. She is a leggy 5'8" and can flat-foot a Goldwing...I will leave the image of her at the MSF class on a Rebel to your imagination!
Her first bike was a 1000cc Suzuki touring bike...she liked it, but much prefers the nimble, thrifty (75+MPG!), tossable Comet.
