As far as in ring performance goes Shawn Michaels will always be better than Triple H. I think both have a good way of doing in ring storytelling very well, but Shawn has that as well as his ability. Neither are good on the mic IMO, they have their moments, but it's not consistent enough for me. Shawn did carry the company on his bad back, high as hell of course in the mid 90's, but it wasn't much of a run because it got away so quick. Triple H on the other hand was IMO the biggest heel of the 90's going on into the modern era, stopping in around 09 or so. Plus Triple H will be heading the company soon or at least have sort of controlling aspect of it, so I think Triple H has made the greater impact in the business although Shawn is the better performer.
