There's the satisfaction of learning and using Highwind/Ungermax, dispite the fact that they are 2 of the easiest limit breaks to get in the whole game. But all of the limit breaks combined could never a) be as difficult to get as Cloud's. Yuffie's is up there, but NEVER harder to get than Cloud's. b) Stronger than Omnislash. (Okay, COMBINED, they can do WAY more damage, but 1-on-1, they do craptacular damage. c)
Be as shiny as Omnislash. Yeah, who can deny the awesomeness of the Omnislash graphics, damage and pride of obtaining it. hat's my two cents.

Stay classy, EyesonFF.
