Mach 3 for me. I also only shave every other day, as my face gets very irritated if I shave every day. So I almost always look like I got up late and didn't have enough time to shave.
I also have a Norelco electric, but rarely use it. I usually end up with terrible razorburn when I do, even when I use it every day for over a month like the directions tell you to. So it sits in the closet where my wife sees it on occasion and reminds me how much she spent on it. :\
Man, sometimes we have really bizarre discussions, for a gaming website...
