when i started, for first couple of years at least, i used to exclusively use an electric and it gave me a super close shave w/ no irritation...
then in college i started using Mach 3 and it was good, not as close as an electric, but still very good, almost efforleess (IF the blade is new)
this morning i used the same electric again for first time in quite a while, and thought it was fast easy and not messy, i went over it with the Mach 3 cuz it missed some spots... irritated the hell out of my skin though after all that... and i sometimes shave w/ only water...
