AMD

I think I had a sapphire once years ago and it was fine. That said honestly what you should be looking for is what their warranty claim processes are like. That's the main important distinction between them, after all. The only other things to research are things like how effective is the cooler, how noisy is it, etc.

I’ve had a few Sapphires and they have been good. I like the easily replaceable fans on some models. Whenever I upgrade I would look to them first. Tuf is ASUS’ budget line afaik so they will be cut back in many ways.
