A list of the best matches to take place at WrestleMania would undoubtedly feature both Michaels and The Undertaker many times over.
In fact, their bouts against each other at WrestleMania XXV and WrestleMania XXVI are in the conversation for the greatest WrestleMania match.
When taking into consideration their overall body of work, however, The Heartbreak Kid gets the nod over The Phenom when it comes to WrestleMania match quality.
HBK has a nearly endless resume of WrestleMania classics against the likes of Razor Ramon, Bret Hart, Chris Jericho, Kurt Angle and Ric Flair.
Taker has also had strong 'Mania matches with CM Punk, Triple H, Batista and Edge, to name a few, but it took many years for him to hit his stride on the WrestleMania stage.
His first good WrestleMania match wasn't until his fifth 'Mania outing, when he faced Diesel at WrestleMania XII, and it can be argued he didn't have a truly great contest until he locked horns with Edge at WrestleMania XXIV.
Conversely, Michaels' first great WrestleMania match was his ladder match with Razor Ramon at WrestleMania X, and he never had a subpar 'Mania contest thereafter.
Michaels' performance level also never dropped off near the end of his career at WrestleMania, while Taker had less-than-stellar matches with Brock Lesnar, Bray Wyatt, Shane McMahon and Roman Reigns.
The middle portion of The Undertaker's WrestleMania career was elite, but the beginning and end left something to be desired. Michaels, however, never looked back after his incredible match against Ramon.
