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.
I am still in doubt about which system, EFI or a dual quad tunnel ram set up, is better for a all out drag race motor
Hence NHRA Pro Stock not going faster now with EFI than they did with dual carbs on a tunnel ram intakes
I remember several different mechanical fuel injector companies testing the location of the injectors heights in there all out race set ups for dirt and asphalt track roundy round all out race cars
