Anakin only beat Dooku because style 2 is weak against style 5
In my honest opinion Anakin was simply just the best Jedi ever to have lived, and this is why he won.
He had the potential to be, but he never actually was. Especially not in the philosophical sense, because he actually didn't understand the jedi way at all. He tried to suppress his emotions until they boiled over instead of controlling them by being at peace with them and letting them rise and dissipate. There were many Jedi who were better than him at using the force, using a lightsaber, strategy etc. and there were literal younglings who had more self control and understanding of the jedi way than him. The only things that truly stood out about him were intelligence in a mechanical sense, raw force-power and athleticism as a fighter.
