Chris Benoit vs. Kurt Angle. Why, well for one their bout at the Rumble in 03 is my all-time favorite match. And they have plenty of other great ones, their three stages of hell (which I believe was just called a two out of thee falls match, but considering the first fall was a singles match, the second was submission only, and the third was a ladder match, I'm calling it a three stages of hell), and their WrestleMania bout to name a few. Why it's better than the others? Simply put the matches are incredible, and with two of my favorite wrestlers of all-time.
Shout-out to HHH/HBK though!
