tool consideration

1 advantage to a 12 pt socket is it usually has a thinner wall to it so if need be you can get it into tighter confined spaces with it. QUOTE]

I feel that the 'thinner wall' also lets the socket expand easier on tight bolts and contributes to it slipping and rounding off of the bolt head and skinning my knuckles (which we learn to ignore and keep working if you've been doing this long enough). Then we get to "feel the burn" when we are finished and go inside and wash our hands...
