The main issue why so many vulnerabilities are linked to Intel is because it's the most widely used. Same thing with windows....most spyware, malware, etc. are designed to attack windows-based systems. Why? Because they are the most widespread...making finding a target, or mass of targets to infect easier.

Back to the point....I have always bought Intel, not because I think their tech is better, it's because of location. I live in South Africa and AMD kind of disappeared here a few years back.
