Shavers seem to depend on your skin type and the length of facial hair.
This shaver takes care of a three-day growth, but if your facial hair is much longer, you will need to clip first, which is what I think you would expect.
I haven't noticed any real difference with the personal settings so not sure whether to class that as more of a gimmick. I love being able to shave in front of a mirror or take it in the shower with me.
That said, this shaver is light and ergonomic and for the price of this shaver in the Braun series, it is very good.
