My 5 favourite matches are thusly:
1. Randy Savage vs. Ricky Steamboat, WrestleMania III
2. Bret Hart vs. British Bulldog, Summerslam 92
3. Chris Benoit vs. Chris Jericho, Royal Rumble 01
4. Bret Hart vs. Roddy Piper, WrestleMania VIII
5. Shawn Michaels vs. Jeff Jarrett, In Your House 2
One I would add under historical significance would be the Savage/HTM match from October 1987. The first meeting of the Megapowers, and Savage's official face turn. A pretty decent little match, too.
I don't know of many people who think Warrior/Rude I was any good. However, Warrior/Rude II, from Summerslam 89, was surprisingly good.
