Who was funnier: opebo or Hawkeye?

[Sam Spade]

A good point is made here:

Both opebo and Hawkeye could be termed "funny" when they first appeared, but both characters had a rather short shelf life in my view.

So, in a certain sense, it's the Simpsons vs. Seinfeld (to simplify things - and neither is anywhere near as funny as those two were)?  The show that knew when to stop or the show that doesn't.
