I eventually gave up and purchased a Google Pixel 4a. I think for "simple" (calls, emails, etc) use on the 3GB Moto X4 (XT-1900-7 Europe), Pixel Experience is fine. But it would occasionally lag when I was trying to type something in Chrome, for example, or when I was trying to play a game. Not all the time... but frequently. Enough that it became annoying. It seemed like... somehow... the memory was out of sync. Sometimes I could write or game for hours with no problem at all. Other times I couldn't go more than a couple of minutes without the phone locking up.
Eventually this would have driven me insane.
Maybe X4 users with 4GB of RAM instead of 3GB never even experience these problems... but I certainly did.
The Pixel 4a is quite a bit smaller than the X4, even though the resolution is much higher and you have more screen area. This is kind of a pain for me since I have big hands. But other than that the experience is better than the X4 in almost every way (except for the lost gestures... which really weren't working properly in Pixel Experience anyway. They would load the camera... but they wouldn't unlock the screen even if there was no screenlock code.)
Anyway... That's my two cents. I'll probably keep using and updating Pixel Experience on my X4 anyway now that I have the 4a to do all the heavy lifting. Probably going to move to the OnePlus 7 Pro or 8 Pro once I have enough money.
