Star Wars: Ranking The Jedi High Council From Worst To Best

Dooku is in much the same boat as Anakin. However, he ranks higher because he served on the Council for a substantial amount of time and even trained under Grand Master Yoda. When he left the Order, he was still held in high esteem as a wise warrior and one of the Order's strongest duelists.

Of course, such a good reputation was cast aside when he joined forces with Palpatine, becoming Darth Tyrannus and leading the Separatist armies during the Clone Wars.
