From my experience, you can't go wrong with the Spigen stuff. I've had some cheaper screen protectors before, and it can be hit or miss with some of that stuff So Spigen is a safe bet
I personally would avoid tempered glass. Fingerprint reader issues and some touch sensitivity loss especially on the sides where the glue is to hold the tempered glass... I personally use a hydro gel screen protector, which I have had no issues with at all.
