There's really no debate to be had on which technology atomises better. You've had at least two people who have worked in the industry say the same thing (Mr P Body and myself). Higher pressure gives better atomisation. EFI is ALWAYS higher pressure therefore, leaving the carb or injector, better atomisation, every time, period.

Per my original reply - what you do with it after that is getting a lot of good discussion here, but there's no uncertainty about which device atomises better.
