i started with the sensor excel and had bad shaves.. then when the mach3 was released i started getting good shaves.. i've always used a brush and never had a problem.. gillette sent me a fusion when it came out and i hated it.. mainly due to the blades being so close and clogging up.. i'd be fine with a mach3 if i had to.. but now i'm shaving with an artist club and it's as good as good is going to get.. i don't see them ever being able to improve on it.
