I use a vibrating Gillette Fusion - It is a lot better than my previous Mach 3 which was not better, but was nicer to my skin than the safety razor I had before that.
I have sensitive skin, and quite soft stubble - basically the perfect face for a multiblade razor. When I was using Mach3 I had to change the head every 3-4weeks.
I have to change the head on my Stealth every 9-12 weeks - that is good vfm IMO to get a high speed, very close, comfortable shave with a razor whose head is cleared by water easily, my 'emergency' tesco own brand 3blade that I keep at work cloggs and requires a nailbrush to clean out.
