Out of all of his opponents, I thought he should have lost to Flair, Batista, and Edge.
I could understand Flair being the one to beat him, as a "return the favor" type deal for them...But you did mention the streak was about to get more notoriety then so WWE couldn't stop it then...
Batista? No...Maybe had the chance for it, but that was a no go. For one, as with Edge, he was going to win a Backlash or at another PPV after Wrestlemania...What had me disappointed at Batista was that HITC match against Taker where Edge came in...I don't know how that was booked, but Batista was horrible in that match...Add the crappy performance against Umaga (who should've gotten that win) and that did it for me as having him be the guy...
Now Edge is probably the closest one out of all of them because he had just about everything...The talent, mic skills, charisma, all of that...Edge has...They put on a hell of a match in Wrestlemania and in that HITC match when Taker returned...He's probably the best overall guy that they have out there now (over Orton, Y2J, and J. Hardy)
