I personally prefer untangling single hooks and find removing them from nets, the flooring and/or my fingers much easier than trebles. I also find with bigger fish that the singles usually hook a little deeper in the mouth i.e. towards the corners. Trebles too often hook towards the front of the mouth, where the jaws are much harder for the barbs to dig into. When the trebles do get engulfed, it makes a mess out of the fish's mouth, tonge, gills etc.
