Kefka vs Pennywise vs The Joker

Pennywise is always overestimated in vs battles.
If you go by just pure feats, then IT isn't that powerful.
It sticks to only one town and scares/eats people. It's not that impressive.

It was defeated by a group of normal children and adults...
Oh, but I guess they only won because they were helped out by the turtle?
Yet isn't the turtle dead by the time they challenge IT as adults?

Just saying...
I have yet to actually read the entire book, but I have read quite a bit about Pennywise's abilities, so I could be completely wrong tbf.

Kefka at his peak still wins imo.
