Best first title winning performances?

Even though it isn't filmed (which is why I didn't have it number one anyway), I'm much more impressed with Saddler vs Pep than I am Ali vs Liston. That said, I completely agree on Napoles vs Cokes. It really is a punch perfect performance.

I can see Hearns' performance being higher. I prefer the drawn out clinic Sal put on, rather than Hearns making quick work of Cuevas. Both were insanely impressive, though. Both showed immense skill and physical ability, just in different proportions.

 

Oh shit!

Forgot to mention Whitaker-Haugen.
