My top five is as follows from what I can recall.
Royal Rumble 2004 (not just because of the result and the action, and that Benoit went the distance for an hour and was strong throughout, but the fact that that match helped set the stage for a lot of matches that would occur at that Wrestlemania)
HHH vs HBK vs Chris Benoit at WM 20 (yeah, what happened three years after that will be forever tainted, but what a closing moment after that match seeing Eddie Guerrero and Chris Benoit hold their world championships high after being in the industry for about 20 years, wrestling all over the world, in Mexico, in Japan, in ECW, in WCW, and made it to WWE and got that big moment at Wrestlemania 20. Those are moments that feels natural in the industry. Moments that Vince would probably love to replicate, but it always looks forced when he tries to script it)
Hiroshi Tanahashi vs Minrou Suzuki (NJPW King of Pro Wrestling 2012). Nothing like seeing a match that goes for 30 minutes and have only one pinfall attempt in it and it was the finisher, but the action and the limb work was pretty compelling.
Hiroshi Tanahashi vs AJ Styles. Day 17 of the G1 Climax in 2015. I never understand when people complain about certain matches and certain wrestlers when they do not "sell" any body part done to them until I saw that match. Those guys went 28 minutes and those guys were limping in agony throughout the match.
Chris Benoit vs Kurt Angle. Royal Rumble 2003. (Yeah, I was a Benoit fan. It hurts what he did to his family, to himself, and to the industry on that day in 2007, but damn dude, that guy had some tremendous matches).
