I think most of 2001's PPV's would top that list. WM 17 had to be the best with just about every match being amazing. Sure, the gimmick battle royal pretty much sucked but I enjoyed the nostalgia of it. And to have Mean Gene and Bobby Heenan call it was icing on the cake. WM17 had monumental matches with TLC 2, a 5 Star Hardcore title match and Austin-Rock 2. The only match that stunk was Ivory-Chyna.
A close second: Invasion (not listed), a dream of WWF vs WCW became reality, with WCW/ECW shutting down, WWE's talent roster exploded. Austin's (re)-heel turn had to be the moment of 01 leading to a stellar feud with Kurt Angle. Sure, the only decent match was Jeff Hardy (back when he was talented) vs Rob Van Dam.
Honorable mention: Backlash 2001... reason: another awesome hardcore title match with Rhyno vs Raven. Just watch it!
