You can order at other places for $9 (for the comp)
but don't ever go by company description... just go by opinions of people who have played with all of them.
My friend just got his arcade with supers and while extremely nice, are very difficult for some moves in fighting games, which aren't difficult on the competitions. I'd also order the heavy springs for the competitions just in case you later decide they're too loose. (Do a forum search for heavy spring or competition heavy spring)
But competitions are definately the best for fighting games out of the two, but I see no reason why they'd be "Worse" than the supers for all other games... so in a way IT is the best all around
