As usual you didn't answer a very simple question directed at you.
There are certain things which EFI can do which a carburetor can't
One of those things is have precision control of fuel metering directly to each individual cylinder.
I would imagine that any conversation where Greg Anderson or Jason Line discuss the virtues of carb over efi would probably be with regard to their respective field of expertise. Pro Stock drag racing. And no, I wouldn't disagree with them.
But I seriously doubt either of them have ever made any specific recommendations in regards to adding a 100 shot of nitrous to a mild street engine which wasn't specifically built for it.
