GNW Tenten is better of course because Cheogsam version is probably only for ninja collectors and there is nothing much you could do with that version

GNW Tenten does a lot more damage because her mystery does all attributes damage and also need less combo to do the chase.

GNW tenten is better for the simply fact that can be used in round 1, since round 2 onwards Tenten Cheongsam is comparable if not better, but in the meta teams she is used only for round 1 mystery, so...

GNW 10 10 is defin8ly better, cuz of her ability 2 use her mystery in the first round, which causes all element attributes 2 the enemy team.

GNW tenten is better by far. Her ability lines up with her mystery pretty well, typically she is used for a round 1 mystery. Cheonsam 1010 isn't even close, not really that helpful unless you're a collector or somethin.
