The Kona's frame is going to be a titch heavier, more trail oriented, where the Specialized will be a XC race geometry.
On the surface, I think that the Specialized is a better spec'd bike. Fox RL fork, compared to a marzocchi MXR, but I do like the Kona's Curb Appeal.
The stumpy's frame is the same across the whole range until you get to an S-Works.
I'd say that the Specialized off the line may be a better buy, but it does come down to what you want, which feels better. We cant decide that for you, that's your job.
Just remember, John Tomac won world cup races on a Raleigh, He probobly would have done it on a Huffy as well.
