I used to hate Samsung's previous design, but OneUI isn't that bad and ads some genuinely better things than stock Android. That being said, I do miss some of the simplicity of stock, plus the genuine speed/responsiveness that it brings.
There are some sites that I can't figure out how to bypass, for example thelogic.co. The full article doesn't seem to load unless you pay/log in and no matter what I've tried it doesn't work.
These have both been in stock for a while... or at least, I ordered a 7900XTX last week and I never saw it go out of stock.
