Ok I gave it a go.
The anti-fingerprinting works exactly as advertised, there's no smudging this screen protector!
As with all screen protectors though, application is a mission, I managed to duff up the first one so had to make sure I managed it with the 2nd one.
The matte finish helps combat reflections from sunlight/windows etc BUT because of this there is a snowy cast on the screen which is obvious on white backgrounds so reading a website or some text will soon feel awkward because of the grainy snow effect.
If you don't want this grainy effect on the screen you can't get the anti-fingerprint version which in turn removes the matte finish so you get reflections...can't have everything you know
I also noticed that even though it removes reflections the way it bounces light around it causes a surface wide patch of lightness when a strong light source is behind you whereas without one the reflection only affects the area the light is casting on, this can be a bit distracting.
It is of higher quality than the cheaper screen protectors though and comes packaged with a squeegee to help iron out air bubbles (it's just a thick piece of card) and a glasses cloth.
Hopefully the with and without the Seinheil below will show you what I mean but it's more obvious in the flesh.

^ Notice what I mean by the surface wide patch of lightness?
