When I first started shaving twin blade razors were just coming in. I have watched over the years with some amusement as the number of blades has gone up, and up.
Personally I never had much luck with electric razors, always irritated my skin for weeks till I "got used to it" and never gave a decent finish.
Now I tend to use a Mach3 and its fine. Change the blade when layers of skin start to come off
Seriously, perhaps where you shave is more important than what you use. I have a shower every morning. 5 mins or so waking up and contemplating my navel under a good jet of water with loads of steam. Wash hair. CLean teeth. Wash face and neck (medicated soap). THEN soap up with same medicated soap and shave. After all that time and moisture the shave is easy and irritation free.
Just a suggestion.
