Only if you don't use a case. It drives me nuts trying to reach the edge of the display but getting blocked by the side of the case, and that's even with a pretty low profile case. I never had that problem with flat screens
For me, the side swiping seems more smooth on the curved screen. I never really noticed missed or over inputs.
While I'm not sure I "prefer" them, I do think it gave the phone a more premium look and feel. There's something about the side scrolling content scrolling around the curve and off the display, and the device felt...thinner, I guess.
And ever iPhone has a flat screen, so the differentiator on the front of the device was instant.
It's definitely got downsides though, and I totally get it.
I have gone without screen protectors for a 4 and a 6. The glass now is different than back in the 2010's. I know it is a big ask/risk and highly dependant on your use case and lifestyle, but you may find that the protector is not actually doing anything any more. All of us are different in how roughly we use phones. I am in the habit of always keeping items in certain pockets, like my front left is always only for my phone, and I have limited physical mobility, so I am not very hard on devices. YEMV
Yeah, glass technology is definitely getting better. But I can never unsee even mirco-scratches, and I don't tend to use a case, so I just take comfort in a screen protector.
I didn't hate the liquid application of screen protectors on curved screens either...it was kinda cool to set those up (even though the fumes were kinda bad).
I can attest to this, after last year. Searching hard for screen protector on the pixel 6 Pro. I kept coming across people who said they never ran one. So I finally took it off and have been going naked for the last year with zero issues. I am basically asking for this phone to break so I can get a new one but so far no issues with the display.
