Of course, in my eyes, there is only one match that can be considered the best. Cena vs. Michaels II, on Raw after Wrestlemania. The match in itself was amazing, and then add on the shock that no one ever expected an hour long match from the two on RAW (or EVER from Cena), and that it was by-far better than the Wrestlemania match between the two, AND that it inspired Chris Jericho to return...

There is no other possible choice.
