Manufacturers generally recommend use of autobrake and idle reverse. This is because the amount of applications of carbon brakes is more significant in reducing wear than the temperature they reach. Autobrake gives you a selected decceleration rate (on the A320, low gives you 1.7metres per second per second for example). Autobrake comes on soon after landing, the reversers take a while and by the time the reversers have taken effect, braking is already under way. The result is that the brakes release a bit to maintain the decceleration rate but the landing run is exactly the same. When the reversers are stowed at typically 70 knots. However, you have changed the brake setting and increased wear.
The trick is to make your turnoff at about 30 knots (70 in Ryanair's case!) achieving the above.
The A380 has an 'exit by' function. You tell the FMGS which exit you wish to use and the autobrake gives you one steady application to make that exit.
