We always make use of reverse thrust. We're often landing close to our maximum landing weight of 630,000 lbs, which means hot brakes if we don't use reverse thrust.

Our landing distance doesn't change with or without reverse, but the brake energy does. In autobrake mode, the system only cares about how fast the airplane is slowing, not what's slowing it down, so the more reverse that's used, the less the brake is applied, and the cooler the brakes are when we park. This is especially important in hot climates, where the brakes tend to cool very slowly, and large fans must sometimes be used to cool the brakes after landing.

When light, such as an empty repositioning leg, we hardly use braking at all, relying largely on reverse thrust.
