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.
I mean, we do, but we did give some of it to Ukraine (not a criticism) and also more importantly, we want to keep having that hoard. I guess who knows wtf our foreign policy is now, but in general if you have a big, one-time-use stick, it's smarter to threaten to use the stick than it is to actually use it and just hope that there's nothing else that needs whacking afterwards.
