which incarnation of the turtles were the best fighters?

If Tournament Fighters were tied to Mirage thanks to the presence of Karai in the SNES/Genesis versions (no Bebop/Rocksteady in any version), Mirage for the win. Sure the Shredder was the weakest, but Battle Nexus seemed to be inspired by a Pokemon tournament (not to say it was bad, but Mirage felt more organically powerful). Ranking them down from best to worst, 4kids would be next, followed by IDW, then Nick, then the Movies, then Archie, the OT, and finally The Next Mutation (at least the OT has some creative slapstick moves along with the good first season).
