There's a lot of gray area between "entirely free of such issues" and "completely unusable." The AMLogic chips on mainline linux are much closer to the latter than the former.
As long as you're on a board with good community usage in Armbian (Odroid is one of the most popular brands and some have official support), I don't think it's much worse than vanilla Ubuntu on any common laptop or desktop.
Pick up a sketchy Android TV box from Ali that's not in the top 3 and yes, you're in for some "fun" times.
