For the OP's sake and everyone else's, I don't want to turn this back in the wrong direction, but "You have to spend more time making a fuel system" and "It also costs money to do it" along with the time for wiring it are drawbacks. It's unfortunate the level to which you have to jump down everyone's throat if they disagree with you. I mean I even agree with almost everything in your post back there. If you just cut out the bloviating I think you can get to a fair answer for the person who asked the question. We know what technology you don't like, it's all on display here for everyone to read and decide how much they believe it.
There are dyno tests that I would say even accurately represent what most people are able or willing to do with a carb and they're +/- a few hp depending on which one even with a sniper vs a carb. The OP wants to enjoy his car not squeeze every last amount of ET out of it. It may never see a dyno. He just wants to get it running well and even I suggested that maybe starting with what he already purchased might be the right move. For example this one is particularly relevant for the original poster:
