To me Gaara because Kazakage Garra doesnt have the demon in him any more. So ppl may say they are like the same so it would be a tie but one has a demon while the other doesnt.

Well considering they're both kind of the same person its kind of hard to choose, but Im going to have to say Kazekage Gaara just because he is the leader on the Village of Sand and you have to have a lot of power to become a leader of a village in Naruto. But thats just my opinion.

regular gaara cuz kazakage gets the "beast within" taken away from him later on in the story

gaara cause kazekage l think loses his jinchuriki plus the future gaara is nicer and the regular gaara wont show any mercy

I would say Gaara since he's more ruthless back then and after he becomes kazekage, he loses shukaku

Gaara because he is ferocious, even if the older knows better technics, in his new character he would contain his self. Anyways he is death. [See naruto Shippuuden 218-224]

regular gaara i think, since gaara's beast power thingy gets taken away.

gaara he's the ultimate killing machine

dark water dragon

everyone has become better than their previous selves... same applies to Gaara I suppose... Kazekage will win...

wait, before or after the loss of shukaku
