Taller is better.
I'm 6'2ft but would love to be even taller - around 6'6ft would feel awesome.
Proportions are important though. Being tall isn't that impressive if your proportions are fucked.
As a short man, Ive always felt like it matters less and less as you get older, especially if youre established in your career and have a family. At that point, no one really cares.
However, I admit that being on the short side can suck growing up during junior high and high school days, although I never outright had a problem. I went to an all black high school, and no one cared that I was on the short side. Instead, I just got called the usual racial slurs (honkey, cracka, etc).
