Sasuke tried to kill one of them and left one for dead but they all understood that he did it out of emo, and that he cares for them all cos right after that they go looking for him and make global domination plans with him. And as for Karin.. the most loyal chick ever, she's psycho and the dude tried to kill her but her passion for him still burns strong, now that's loyalty (she gives me a boner tbh). Team 7 was nothing without Sasuke and now that Naruto has gain strength they may be a proper group, but it is still nothing against team Taka cos they beat team 7 in every way and Sasuke alone could solo the entire team if batlle time came, Karin is smarter than Sakura, has better healing and is a better healer and sensor (also has better Chakra control and worlds more of chakra on her). Suigetsu is more dynamic than Sai and can easily defeat him (indestructible water style body defence plus silent killing and suiton over glorified drawings). Jugo is superior to Kakashi and can easily kill him if he just lets lose (we all know that for a fact.. the only people to have survived his rampage are Sasuke (Uchiha son of the sage so he's OP and Kimimaro (some connection to kaguya, also OP))) so Kakashi is fodder in comparison.
Sasuke and Naruto.. on par, Naruto has brute strength and destructive power while Sasuke has intellect and tactile fighting style so they even out but Izanagi tips it in Sasuke's favour should he chose to sacrifice his eye to end things for good (highly unlikely cos he loves his eyes).
so there it is, Taka >>>> Team 7.
