> I was pleasantly surprised with the OnePlus. Little bloat, compared to Samsung, hardware is very solid, didn't notice any glaring software issues, no weird stuff. I'm not sure how open it is to flashing another ROM, but to me it feels like a higher end Nexus phone.

OnePlus is one of the two (the other being Google) manufacturers with absolutely stellar custom ROM support IMHO (if there are others I'm missing, I'd love to know) (:

And even their stock ROM is pretty damn clean and good as well, last I checked. It's really impressive.

Literally, the OnePlus 9 Pro (latest model) has an official LineageOS release. I don't doubt there are plenty of ROMs for the 9 as well and there will soon be an official 9 LineageOS release. Hell, the OnePlus One has an Android 11 official build on LineageOS's website.

I've been daily driving a OnePlus 6 for the past three years. After OxygenOS 10, I switched to LineageOS for Android 11 and the phone is just as fast and smooth as ever. Extremely, extremely satisfied with my OnePlus phone, although I may be trying Google this time around because the Pixel 6 is cheap.
