Which is the better, best electric shaver for a young man 18 who doesn't have very much of a beard mostly blonde peach fuzz?

Philips and Braun both are good brands. Personally I like Philips.
As someone mentioned, good to have wet option. Makes shaving smooth and easy on skin.
Before deciding, think how he will use it. Do he keep beard and like to trim? Then there are other options you should look.
