While you're using in-movie examples, you might want to toss in Anakin's desire to become "as wise as master Yoda, and as powerful as master Windu". Don't start tossing around "you need to watch the movie again" platitudes until you can be sure that you're immune from them yourself 😛
And as for Sidious and Yoda being exact equals, I don't see it. From what I could tell, Sidious tried to flee, and even in his choice setting, Yoda had the distinct advantage throughout the entire fight. He left mostly because he realized that even he couldn't stand up to a whole squad of clone troopers AND sidious.
