TBH, I think he scores a stoppage over a Reid that is past it. Possibly in the 5th round (maybe a corner stoppage) after flooring Reid several times, although Reid will hit Froch with some good shots and have a couple of decent moments. Still I could be wrong...
Prime vs prime is an Reid stoppage. Reid had a great right hand, he managed to stun Froch multiple times when shot. Froch is ridiculous open to that shot and in his prime Reid destroys him, different class of fighter.
Its a difficult one because excellent fighter though he was, he was guilty of having very bad 'off nights'. If they are both on top of their game on the night then it's a difficult fight to call. My head always seems to be telling me Froch gets beat, but he ALWAYS find a way to win. The guy just doesn't understand the concept of losing.
