How to quickly compare iPhone models

I’m starting to think about swapping out my XS for another model and came across the compare iPhone models site. I’m struggling with the screen a bit on my XS, I can visibly see the flicker from the OLED refresh rate and finding my eyes getting tired using it. FaceID continues to frustrate and I’m not convinced it’s entirely safe to use for long periods so I’m looking at older models and what I’d be losing dropping the camera down a few years. This Apple site makes it super easy to check the differences.
