For trails it's great. The shock lockout indeed not a full lockout but it is almost never used as the pro-pedal feature works well for most situations. The components on the base stumpjumper are just about perfect. The tires aren't great for traction, but whatever just rip em and get new tires once they're worn. The bike rides rolls a tank since the tires are so wide, the howl on concrete is SWEET!
