Edge/Christian vs Dudleys vs Hardys
Benoit vs Angle vs Jericho
HHH vs Rock vs Foley vs Big Show .. with the ultimate swerve ending.
Benoit vs Angle vs Jericho was average at best and Triple H vs Rock vs Foley vs Big Show wasn't that good to be honest. The only good part about that match was the ending with The Rock laying the Smackdown on the McMahon/Helmsly's asses. The Triple Threat ladder match between Edge and Christian, the Dudleys, and the Hardy Boyz was the only memorable thing about that WrestleMania. WrestleMania 2000 was a big disappointment but they made up for it by giving us an awesome Backlash 2000 PPV.
For me, my top WrestleMania events are WrestleMania X-Seven, WrestleMania 20, and WrestleMania 19. Honorable mentions are WrestleMania 10 and WrestleMania 3.
WM8 - Piper - Hart (sleeperhold reversal pin win)
WM 14 - Michaels/DX/Tyson angle - plus Kane and Taker's match promo and Taker's entrance
WM 15 - Rock - Austin (stunning) and Taker hanging BBM from the Hell in the Cell.
The cliche X-7 and XIX are my top two and it's a big drop off after that. XXVI and XXIV were very solid cards, but I need to go with Wrestlemania VII. It's not because it was great or anything, but out of pure nostalgia as the first WM after I started watching.
