Samsung is a no-go, it’s always a fight with them (I know, I still have my old S4’s). You can root them, but it’s a pain, they have stuff like Knox that always wants to run, yadda yadda.
Pixel is the way to go. Also the Essential Ph1, which, whole being from 2017, can run Lineage Android 13 and is still blazing fast.
Wish I could give you a second upvote for “tighter than my ex”, haha!
