Dude, Squall & Cloud defeats anything in Instant.

Cloud is forced into Teamwork when trying to defeat the overboosted Sephiroth at the end. (And requires an expendable death)
Cloud, I'm sure, would own Sephiroth any time giving he would have had the choice to do so.

Squall is only at his first mission (second if you count Laguna, Martine wasn't really a real Garden mission). Imagine how strong he'll be when he does more missions.

The fact thoses F-C SOLDIERS were defeated (and died) by the hands of an insignificant class soldier just proves how some F-C SOLDIERS sucks (Except Zack). Espescially when Squall was penetrated by a powerfull Sorceress and didn't died. (No wound, in fact).

During the Garden Confrontation, each sides could've had easily defeated or captured the enemy without necesarily finishing them off.

If you don't based yourself on game mechanic or abilities, what are you basing yourself on? Shape & Size, and the amount of energy they've received by other powers?
That doesn't prove much.
