There are so many personal preferences involved that it's impossible to give a solid answer to that. Might as well ask what's the best candy. Besides, Scott or Trek doesn't say that much, you've got to compare what components they have to be able to learn anything about them.
Both Trek and Fuji makes several different models, so w/o knowing which models you're thinking of there's no way of telling.

Cross Country. It incorporates running. I do cross country, but not track... in the track season I play softball! :) I think you should to XC if you can run at least 2 miles without getting tired!!! -------------------------------------------------------------------------------------------------- Here is a trick, NOTHING can replace running. NOTHING, cross-country would be best. I did cross-country first then did track to keep me in the running mood. Cross-country is a very good running sport, and is much more competitive. But sometimes you're better at sprinting than running distance, or sometimes you're better at distance than sprinting. Try it out and see if you like it!
there is mountain biking in the olympics, there is only xc at the moment though
Cross Mountain Mine disaster happened in 1911.
