Both. Grow a beard for about 3 weeks, then use the beard trimmer on electric razor to get it low down, then wet shave it all off.
Wet - Every morning and again at night if going out. Tried electric and apart from not cutting close enough, it leaves your face feeling dry and mucky.
Mach 3. Always have done, always will. None of this 5 blade crap, feels like I'm rubbing a cheese grater across my face.
Speaking as one who has sensitive skin, an electric shave brings me out in a dry rash. Wet shaving leaves me cut to shreds, however, palmolive sensitive gel seems to do the business even after 4/5 days growth (with a double edged blade - gosh i hate that word)
I use hair clippers with no guard and do mi head and face with it every two days, do my arm pits and ball bag on number 2 twice a month
