Yeah, there are plenty of Jedi who can beat Anakin, but I think if you normalize for experience, he was easily the strongest of any of his peers. He should have seen being allowed to sit in on the council at his age as an enormous honor. But of course, he’s the egotist supreme, and he had unwise words being whispered in his ear.

Also, in the fight with Dooku, it seems likely to me that Palpatine somehow invisibly sabotaged him once Obi-Wan was down. Palps wanted that to end with both Dooku AND Obi-Wan dead.
