Sounds like you've had a previous "bad experience" with the AMD products and that's colouring your thinking - not saying that's bad, mainly because I said exactly the same thing in my original post, but for NVidia. Me, I tend to look at value for money - if AMD can match NVidia's performance but at a cheaper price point then I'm interested.
Of course the driver issues are "specific" - I did say that I'd defected because of the dissatisfaction with drivers. Oh, and "for years now" no reboot? Colour me dubious, although I've not had the pleasure of desktop NVidia drivers since March 2013 - before which time pretty much every install of WHQL has needed that Windows-usual system restart.. Yes, I know about custom, (and used it) but I'm less than impressed that every install had to have all that unnecessary manure explicitly removed. To my simplistic way of thinking, if you're "upgrading" graphics drivers then you should just get that alone - not a couple of mega of extraneous bloat that some "expert" in NVidia's marketing department has decided I needed. Opt-in please guys!
I'll probably go back to NVidia in a year or two - mainly because NVidia's Linux drivers are better than their AMD compatriots and that's becoming more of an issue for me. As I've said in the past, I'm using AMD+AMD at the moment, but there's no intellectual objection in my mind to going Intel+NVidia for the next build.
