26. The Undertaker vs. Shawn Michaels
Source:hechairshot.com
These two really have a history. They wrestled on several occasions throughout the mid-1990s, but their duel at WrestleMania XXV was one of most memorable (especially when you consider that it was their first clash after some time). What makes this feud even more interesting is that these two guys are the two rare ones that managed to hold on since the Attitude Era and the fact that they are WWF guys their entire career. Thanks to their long history, it didn’t take a lot of effort to interest viewers in seeing Mr. WrestleMania battle The Deadman. Their match at WrestleMania XXV was great, but no one could expect to see a better one a year later at WrestleMania XXVI.
