I actually perfer my mountain bike for longer rides/day tours (which is all I've done so far) I can cover 100 miles a day on it no problem, much more comfortable then the road bike, I wish for the drop bars sometimes, but it isn't bad if I wear gloves and take a break every once and a while. My road bike is a racing bike so it's built for speed not comfort, for shorter rides it's a blast but for longer rides I perfer the slower mountain bike, even if it's harder work sometimes.
