I think it depends a lot on how you handle your phone. I used to have screen protectors, which would always end up scratched, coming off, etc. It was a total PITA to replace them. The last one I had was on my iPhone 7. Took it off for the last 4 years of use I've got out of that phone. The screen is still like new. For mew new phone, I didn't bother with a screen protector. It's a year and a half old now, and no scratch to report.
