Was Frieza the best villain in the DragonBall series?

Frieza was a great villain in Dragon Ball. I'm not sure he was the best, but very, very good, which counts for a lot. Being the de facto ruler of the Universe 7, he controlled his very own imperial army which was awesome.

He was feared due to his ruthlessness and had a whole ton of power. Frieza is the descendant of Chilled, so he is the second born son of King Cold, and he is the younger brother of Cooler, and is also the father of Kuriza. But he is not, in my opinion, the best or worst villain.
