I'm a SF player.... (well... not an expert...)
but I do prefer Competition than Super...
I mean... Super is round and good... and smooth...
but when I block down (down left or down right).... I need to know that I'm hitting the corner...
when I'm using Super... some of the times... I think I'm blocking... but however... I'm actually just pressing down (cos my angle is wrong...) and I cannot feel it....
but when using Competition, I KNOW I'm hitting the corner... (when I press it that way....) no miss... much better....
now... with the Japanese sticks.... I'm pretty sure the Jap. team didn't win the US team with Zangief... haaa haa haa...
cos its next to impossible to pull those 360 spin moves out.... but for Ryu and others that only uses quarter circle or half circles... those are manageable....
my $0.02 of personal opinion....
