Eddie Guerrero vs Rey Mysterio from Halloween Havoc '97 where Rey's mask was on the line against Eddie's Cruiserweight title is still my favorite cruiserweight match of all time. Feel free to share yours, doesn't have to be restricted to WWE and WCW.
Also, that time when Jericho countered Rey Rey's hurricanrana attempt from the top rope into the Liontamer was pretty cool. I haven't followed Malenko's work as closely. Looking for some recommendations
