I give it to Gaara's team. Little kid Gaara already beat Kimimaro. Many of Mei's spore and poison techniques could be avoided due to Temari's fan and it's ability to literally blow shit out of the way. All that's left then is Darui and Kankuro. Darui can probably beat him but I don't think it will take Gaara too long to finish of Kimimaro so it becomes 2 vs 1 pretty quick.
