Which is supported by what? Maul pushing the ship over the cliff in Revival? If so, what supports the fact that Kenobi can't do the same?
Which shows that he's more lethal than those other opponents, but not more lethal than Kenobi. Because Dooku seemed to be more lethal against Kenobi than Anakin was, but that doesn't make Dooku more superior than Anakin as of ROTS now does it?
Because Maul knocked him out with the Force. And he easily levitated him earlier with the Force. He also easily Force Choked Kenobi in a one on one in the Comic Sith Hunters set in between seasons 4 and 5 of TCW which has a special thanks to Dave Filoni and Katie Lucas.
So if you think Kenobi is a match for him in the force then your the only one. So it's for you to prove that. Not for me to assume for absolutely no reason that Kenobi can do the same feats.
I can't imagine Obi-Wan equaling Maul in skill or power in the Force and allowing himself to be ragdolled by Maul as frequently as he has been.
Off the top of my head, Obi-Wan has been on the receiving end of a Force pimpsmack from Maul in almost every encounter between them. Once in TPM, once in Sith Hunters, twice in "Revival," and once in "The Lawless" (though, to be fair, Obi-Wan was clearly dazed there).
Even if we disregard Maul's greater power, it cannot be denied that he is infinitely more skilled and clever in the application of the Force in combat than is Obi-Wan.
Not specified as far as I remember. But we do know Obi-Wan and the Jedi had been hunting for him between Seasons 4 & 5. The comic was about one of those failed missions to capture the Brothers.
I don't think Maul is particularly more powerful in the force than CW/ROTS Kenobi. I do think, though, that he is more accustomed to using it in fights, and does use it more effectively.
There is merit to your argument, I think. Feats alone do not confer absolute superiority: simply because Maul can tug starships around like a child's toy doesn't necessarily mean that Obi-Wan is incapable of it.
That said, it is difficult to ignore the consistent trend of Obi-Wan channeling the Fail Side of the Force with respect to TK in fights. I'd probably say that Maul is stronger in the Force/the dark side than is Obi-Wan, but that's due to a number of factors.
Obi-Wan has used the force a little in fights. Against Grievous most notably, against Anakin, and he did use it in his first fight with Maul to keep the guy off balance, so he's not entirely useless.
