I don’t know much about the Trek but I can speak for the Stumpy. My wife and another friend of mine both ride the FSR Comp (closer to $2000 I think) and they love it! I’ve ridden it myself and the FSR suspension that Specialized patented is pretty amazing. It is almost impossible to get the rear tire to lose it’s grip no matter how steep the climb or how far forward you’re leaning. It really excels in the snow too. I’d say you probably can’t go wrong either way – definitely try them out before you buy. Good luck!
