I got a ROG Phone 3 recently, and while it does come with some OEM software, most of it is actually pretty useful. The only obvious "yeah you were paid to put this crap on my phone, not because you thought it improved the experience" application was Netflix, which - while entirely useless to me - is a pretty decent showing as far as OEM bloatware goes.

Still not quite as clean as a Nexus/Pixel but the best install experience I've ever had on any non-Google device, and the only one I've ever decided not to install a fresh ROM on.
