A lot of V-Brakes actually work as well as disc in ideal conditions. I would go with the Hardrock regardless of what you're intentions are with the bikes though. The Hardrock has the lightest frame in its price range & everything on it appears to be just a little bit better than the Trek. It has double-wall rims (less likely to come untrue), Avid BB5 disc brakes, SRAM X4 rear derailleur. Lockout (for me) is essential for road riding. Some people don't care about it (especially only doing 10 miles at a time) but to me I just hate having my bike bob up & down every time I shift me weight.
