I just got a pair of Roga's and really like them. I'm usually a borderline x-small / small, and the small fits me well. They are a little shorter than I'm used to, but not "too short."
I have both, and strongly prefer the Game Day. I have a Small in both and think I'd like the Roga's more if I had the Medium. I feel a little self conscious in the Roga's and they do ride up a tiny bit. The Game Day are perfection for me.
