Holley's science vs Edelbrock simplicity?

I have had a few Holleys, and never again. I am NOT saying they aren't good carbs, I just had a lot of trouble with them. I might just have had a few stinkers, but twice burned. As a side story, I paid big bucks for a set of Michelin tires several years ago. They were terrible. My car went from a nice smooth ride to riding like a lumber wagon. Although most people like them, I had one bad experience, and that was enough. So bottom line is that one or two bad experiences is enough to turn a person against something no matter how many others love the item.
