Who was a worthier opponent for Shawn Michaels at Wrestlemania, Ric Flair or Undertaker? Why?

WQ2 : If Taker vs Jericho and HHH vs HBK in a HBK's farewell match really happen at WM 26, it's obvious HHH vs HBK already won the emotional atmosphere, right? Do u think it will take anything away from Taker vs Jericho's match quality? Why?
