Simon,
As pilots we always use manual landings unless the weather conditions dictate an autoland. (Fog or reduced visibility) or for practice.
Probably depending on where you fly less than 1% of the time.
Aircraft are either fully automatic or manual landings.
We can fly a full automatic landing using CAT II ILS, however the minimas
(height and visibility have to be higher than if using CAT III ILS)
We don't have automatic reverse thrust. Done manually.
Hope this helps,
Oz
