Personal experience is well and good, but there's no rational basis beyond that for NVIDIA > AMD. That said, you're an idiot if you don't go and look around for what experiences people have talked about, and if your usage patterns match those of people who've had problems, maybe stay away from that brand. I've not had a single issue in the several years I've had ATI cards. As I said, my current one has barely been switched off in ~18 months (closer to 2 years now i think) and it's even been overclocked. And it's played more than just sc2 in that time.
If we're all going to get our panties in a twist about brands we personally don't like, I'd be telling people to never touch Western Digital hard drives with a 10 foot pole. And pretty much all my close friends in real life agree completely. For some reason we all have had terrible terrible luck with that brand. Hard drives failing in under a week, being replaced multiple times, etc. etc. But I generally don't because it's not like it's a truly horrible product if so many knowledgeable people recommend it. It's just that I have had bad luck in the past.
