Clippers are still sharp, can still cause razor burn-like damage, can still jam, can still benefit from some hair being wet etc. I've worn a #1 or #2 all over for half my life now and have had incompetent stylists give me severe razor burn-like irritation, pull at my hair with clippers that weren't well maintained, be quite aggressive with the pressure over my scalp, regularly miss strands here and there that I then find days later in the mirror and have to trim with scissors, etc. You can also put a guard on clippers and get varying lengths of hair remaining due to the angle, then of course lining up sideburns/removing sideburns/squaring the back/leaving the back natural/cutting my widow's peak down to the skin without asking me (which many people want) etc.
