Who's put on better matches: HBK vs Undertaker or CM Punk vs. Rey Mysterio?

I'd have to go against the popular vote and go with Punk/Mysterio, only because they have much better ring ability than HBK and the Undertaker. At this point in time, or even up to 5 years ago, I think HBK/Taker would recieve much more hype and be given much bigger credit, but on in-ring performance, Punk/Rey is much better.
