Rollins probably on a move-to-move basis with Ziggler as a very close second (considering I only bother to watch PPVs now, my answer will probably change depending on who had the best sell out of the night out the two of them) but in term of long-term selling, the stuff that I care more about, I'll still go with CM Punk. Can't really make a strong case here as I don't watch a lot of WWE right now but I'd give him the nod back when I still watched it and nobody from the last PPV or two really stood out to me in terms of long-term selling so Punk wins it by default.
