Ride both and see which one you like best. Is there a problem with keeping both bikes? You might find different reasons to like each one, or keep them around long enough to see which one you develop a stronger preference for. The Giant is a road bike, and the Conquest is more of a cyclocross bike. So the Giant is strictly for pavement riding, the conquest can go on gravel. Ride at least an hour on each bike a few times and see which one is better.
