My guess is that their 'best' blades are all pretty much the same.
The closest shave I can get is actually the old safety razor double edged blades, but they're hard on your face... or used to be, haven't used one in some time. My son uses one and swears by it - it's a newer one and I read that they are much improved since the old days.
You might remember that I bought an electric razor some time back... I think it was a Panosonic and it was their best model. Very expensive. It was ok... not a bad shave although certainly NOT like a blade. I got used to it, used it just under a year and it broke. That killed them for me... I may have just had some bad luck but I'm not spending that kind of money again for something that lasts less than year.
