Leaving One+ ecosystem, decent phones & nightmare support & service

Hi! The Oxygen 16 OTA rendered the touchscreen on my 12 Pro unusable and it took weeks to qualify me for repair return, then their service contractor had the phone for a month without communication, then they shipped it back without packing material in a smashed box left outdoors in double-digit-below-zero weather without labeling warning not to do that, and they had removed and retained the SIM tray rendering the phone inoperable in any event. I had to buy a third party SIM tray, then mine arrived back from them after weeks of numerous unanswered emails, followed by an offer of a $10 gift voucher. On balance, entirely awful experience.

I live in a remote, rural area where being without reliable communication is death-defying.

That was about three weeks ago and now the same thing is happening: the touchscreen is becoming unresponsive. I can turn the display off but it only comes on after random number of attempts. I could shut down to bootloader (I think? I get that confused with Recovery. It's the one with language selection.) but then I can't get it to properly reboot because that too requires a tap.

When I can get it to reboot the touchscreen sometimes works fine for awhile (a shrinking while). But sometimes not. Attempting to reboot is taking up a large part of my day.

Thinking of a Pixel 10; any thoughts?

Any strongly-held suggestions, particularly on my backup/restore options, going to a different phone?

Very sad to leave OnePlus. We have had several. I feel they owe me a new phone. I'd be happy with a reconditioned 12 or up, if it just worked. But I am not envisioning that likelihood.
