1) Kimimaro: If kyubi naruto > a jounin w/ hero water, then the hero water isn't all its hyped up to be.......
2) Sasuke: The gates was what gave lee the edge over sasuke....at least at this point, where sasuke's taijutsu is as fast as lee's.
3) Gaara: It would be an interesting fight, especially if the kaiten really is a "superior" absolute defense over gaara's sand. However I still don't see how neji can physically harm gaara.
4) Gai: But only if gai can unlock gates.
5) Zabuza: We've seen how the kaguya clan stands against Mist jounins....it isnt pretty. If kimimaro can't use his curse seal, then that probably means he can't do broke stunts like encase his body in spikes or create an impenetrable skeleton.
6) Neji: It's a tough call. Theoretically, Uchiha should be > Hyuuga, however being older, Neji has more experience. Also I imagine his kaiten can beat most of sasuke's attacks. But then again, with sasuke's offense and neji's defense, it might be more of a question as to who will run out of chakra first.
7) Zabuza and Haku: same reasons as #5, except to an even greater extent
