Not really. I hate Austin/Rock II and think it's fucking dumb. I find HHH/Taker also hugely overblown as time goes on. It's nothing special. TLC is a spot fest and I've recently fallen out of favor with them as a match type, and Angle/Benoit is an amazing match.
I think what sets Mania X-Seven out from others is the fact that the crowd ate everything given to them. That crowd in Texas was fucking rabid, man.
Personally, XIX has better marquee matches if you ask me. Angle/Lesnar is a great match but shouldn't have been the ME, Austin/Rock III is a much better match in my opinion than II, Hogan/McMahon is a great fun time, and Jericho/Michaels is one of those dream matches a lot of people had.
As for III, I just personally find it more enjoyable than any other mania. Does it necessarily have better matches? No, it really has Savage/Steamboat and that's it, but it had something for everyone to enjoy, which is what mattered most. That and you had the most important spot in WWE history with Hogan slamming Andre.
