I am 6'3" 300 lbs. I own the rockhopper comp disc. It has stood up to my mass very well over the last few months of pounding on the trails. In fact only one thing has gone wrong and that was a broken spoke. No big deal considering my weight and that i was going very slow around a downhill turn on pavement with really sticky tires. Thats a lot of tortion
So, don't worry about the frame strength! The Specialized has better components and is probably lighter overall, which wasn't a concern for me! :-p I love the Tora fork.
I would get whichever one you could get cheaper.
