Match with Flair at WM is MOTN for me. 2 of the GOAT going at it with a great feud behind them and having a great match. Way better than the Hogan/Rock match which might have been bigger on paper, but had a shitty feud going into it and a good match with a great crowd.
I too love the hardcore match with RVD from Vengeance 01. Got the PPV on my PC, and every now and then when I'm bored I'll watch that match lol. Undertaker was so awesome around that point. Shame he had to drop the belt to Maven. But he got the Undisputed title after that
