In some terrain, rear suspension is advantageous both in climbing and descending. When descending, it keeps wheel planted on the ground for better control and braking. When climbing rough terrain, it similarly can keep the back wheel planted for better traction. Some folks also get bikes with rear suspension because it limits stress on the torso and knees when hitting bumps.
