Used to prefer Keo but now find that it has a little too much gas in it for my taste, ok if I leave a bottle open for a while before consumption. Carlsberg seems to have improved with age, rather like myself and is an easy beer to reach oblivion on.
Never drink either on tap and prefer bottles (large) to silly cans (small), that way I can drink and feel satisfied that I'm going to get £1.87 or whatever it is back on the crate of empties.
