Bret Hart vs The Rock - this is a hard one as i watched many matches between hart and hbk in my time and there fued for me was the best thing the wwf ever done. but in saying that i will have to choose the rock because not only does he have the wrestling skills but his Microphone skills are second to none and his entertainment value has been the best the wwe has seen.
Austin vs HBK - quite easy one HBK wins hands down in all areas of the game. from a 17yo tag team partner to the showstopper he became in the mid to late 90's. every moment of his career has been one massive highlight.
Angle vs Hogan - I have to go with Hogan on this one, he has done more for wrestling then anyone has ever. When the nWo started it was the beggining of the WCW. Before nWo no one cared and they put WCW on the map.
I would like to say though all these 6 men including a few other (Taker,Flair,Owen and many others) the sport which is wrestling would not be has world known and as good as it is today. These guys set the bench mark for every superstar you see before you today.
some matches that has involved these men have been;
HBK vs Hart (1 hour iron man match)
Hart vs Hart Fued
DX vs Hart Foundation Fued
Hogan vs everyone (i honestly can say he has played with the best in the buisness and there are too many matches in his carerr to even know where to start)
The Rock vs Foley (I quit match) by the way mick I QUIT I QUIT I QUIIIIIIT hahaha classic
Angle vs HBK recent match
Ps: great threads who ever started it all. any of these men deserve to win it.
Austin vs
And just a great, all-round entertainer and so likeable.
