Villain Critique Choices

I have two choices to pick between that I want to do a villain critique for: Count Bleck and Dimentio, both from Super Paper Mario. The problem is that I don't know which one to pick first since both of them are very great, well-written, and nuanced villains.

So, I've decided to do a sub series where I let you choose which two or more villains that you would like to see me do a review on and why.

Which of these two villains would you like me to critique in the next Villain Critique?
