This is something I've seen dozens of times over the years (and I'm old!). Someone has a problem with a carb, they want to junk it and buy another brand.
Or, turns out it's not even the carb. A vacuum leak, faulty ignition, or just incorrect timing, or dwell settings. Then either the carb swap inadvertently fixes it (which is possible in the case of the vacuum leak), they do several changes at the same time that end up fixing the problem, or the problem gets fixed after they realize it's still running wrong with the new brand carb. In most of these cases what they remember later on is <insert brand here> made it run like cow pies
I don't see any need for carb wars, as any brand will run correctly for a long time if setup right (assuming your not running a knockoff of the original brand, in which case, all bets are off).
