Anybody with half a brain can understand they are talking about a properly tuned setup, a properly tuned carb will give the engine what it wants, with efi YOU tell the engine what it wants and you better be SMART enough to know how to tune it correctly. I've seen too many carb'd engines go down the track pig fat, slow but living to make another run, the flipside is I've seen just as many fast, high powered power adder cars with efi **** the bed half way down the track cause the dude don't know how to tune.
