Here's what I think of this one. TPM Kenobi killed Maul, though it was after bot were already a little tired from fighting, especially Maul. But I think that AOTC Kenobi can defeat Maul. Boba is extremely strong in the EU, and has been able to hold off Vader before. If he can manage being able to hide behind crates and fighters in the hanger and randomly barrage Vader with attacks while Obi is killing Maul, then the two of them could try to ambush Vader, though that unfortunately might not work....unless Boba uses his disintegrater and Kenobi is in berserk mode, Vader wins.
