Gaara healing better than Tsunade.
Before you read and troll, the title was just a attention grabber. Just talking about the potential gaara has to heal better than Tsunade.
Now, I was thinking of when Pein invaded and Tsunade used her slugs to heal all of the living villagers. She put her chakra through the slugs, and into the people.
My logic is, that if Gaara decided to learn to heal, he could do the same, but with sand. He runs his chakra through the sand to move it, so why not do the same to heal? The sand could cover a lot more area than slugs, and could potentially heal more people.
I'm not saying that Tsunade isn't a great healer, she is clearly the best at the moment. Simply stating that with Gaara's large chakra pool, and his mastery of the sand, he could heal a village with less strain that Tsunade.
