I'm a little clumsy and have kids coming round, so some protection is useful.Really I've not used a screen protector for years, only had one on the S22 Ultra last year for a short while before binning it off. Screen to this day remains mark-free.
Unless you are quite clumsy, then not needed. Victus+ was great for stopping scratches, Victus 2 on the 23 is no doubt going to be better still.
