I'm a big fan of anti-reflective screen protectors, I have these on my iPhone 13 Pro Max.
pros:
-it had a bezel and the edges curve downwards
-the cutouts are very precise
-antireflective material doesn't impede the quality of the image
cons:
-it loses anti-reflective coating over time which tend to make it somewhat ugly
-only comes with one out of the box however...
Hoda has stores in Asia at every major shopping center so every time I take a trip to Singapore or Thailand($30USD) I just pay to have them install a new one for me. I'm on my 2nd one.
For my IPP13 I have the Astropad V3, which is not nearly as good and has zero shatter protection. The Astropad also yellows relatively quickly so image quality isn't the best.
