What is the best WWE match ever?

It has long been argued by Wrestling insiders that Ric Flair v. Ricky Steamboat at Wrestlewar '89 is the greatest match in pro wrestling history. I thought they topped that at Chi-Town Heat that same year.

I say it would have to be Undertaker vs. Batista at wrestlemania 23

I would say this years Royal Rumble match because of John Cena's return to the wwe.

Undertaker vs. Shawn Michaels at Wrestemania 25
