I just don't know how anyone can think that Anakin was the strongest in ROTS. Yoda would hand him his ass, Windu would beat him in a good battle, and Obi wan DID beat him. Palpy would also kick the living crap out of him, no matter what Anakin says he can do.
Don't forget, he vowed never to fail in AOTC after his mom died, and 30 minutes later he lost his arm to Dooku. Then he was talking shit to Obi wan like he is going to kill him now, and then 5 minutes later lost both his legs. Apparently going into the suit didn't help him mussle his arrogance, because he was also talking shit to Luke in ROTJ, and moments later lost his arm and caught a hard beat down again.
Anakin is a shit talking fool, with no game to back it up. He had the most potential of course, but potential doesn't equal game. Face it, Anakin is like the 4th strongest Jedi / Sith in ROTS, and that was at his peak.
And saying Obi wan only won because he knew all Anakins moves is just rediculous. Did Anakin have his freaking eyes closed for the 10 years that Obi wan trained him? Don't you think he picked up a thing or two about his masters moves? Fact is, they know eachother equally well, so that point is MUTE. There is no advantage or disadvantage on either side, because they both know eachother. No, obi wan won because he is a better in combat. Sure he is mostly defensive, but that is his style, and it works amazingly well.
If you guys had your way, Anakin would be burning in the fire and he would shout back to Obi wan: "Hey you cheated, no fair. You played too defensively. How come you didn't fight me in such a way that would let me win? Bastard, I hate you. Cheater, cheater... you were defensive you cheater... "
Vanquish do you know something that George Lucas doesn't, because he wrote the movie and in it Anakin says that he is more powerful than Palpatine. Also in the RotS book which IS CANON WIndu says that Anakin is the most powerful jedi ever. So you are talking out of your ass. Unless you wrote the movie/book, then you have to go by what is said in the movie and book. And it was said that Anakin was the most powerful. You are coming off as a know it all. I am glad that you have an opinion and everything, that's why I come to these boards. So that I can analyze and discuss what I love. Star Wars.
Anakin could have become the most powerful ever if he didn't messed up. He droped the ball plain and simple. He didn't learned the full potential of the light side neither the dark side. And what made Obi 1 win in mustafar was the fact that anakin once more, droped the ball. Should he waited and jump a few meters far from obi he would have made it and keep dueling. Obi warned him that he was on a higher level and that he would not make the jump. Anakin is just too headstrong.
