Best Anti-Reflective Screen Protectors

[ShaneBunting]

I hate screen protectors with a passion, but using my iPad 2017 could really be improved with a nice antiglare and preferable privacy one.

3M has a good looking option for about £30, are there any lower cost but just as good products?

Zagg offers a privacy tempered glass if I'm not mistaken
I prefer normal tempered glass as privacy screen protector tend to not offer 100% clarity.
