I've had the same experience on desktop & mobile. The desktop issues with Radeon are from quite some time ago, but the driver problems on both Windows & Linux back then were extremely frustrating: random framerate slowdowns, no working linux drivers, bad support in some games, ...

And the only time a Laptop has died on me was when its AMD GPU decided to go crazy, resulting in artifacts and full system shutdown within a few seconds/minutes, if you were lucky enough to get it booting at all.

I know that this is anecdotal and most likely just coincidence, but I haven't had such problems with nvidia, so that I'm willing to pay the small premium price whenever I need a new GPU.
