Which is more preferred for best atomization? Or are they the same results?

Lets say I needed 500cc/min of WAI (water/alcohol injection) just as an example baseline number.

Would it be better to get a 220psi pump with the appropriate nozzle, or better to get a 150psi pump with the appropriate nozzle?

Given that both pump/nozzle setups supply the same cc/min, would a higher psi pump atomize the WAI better?

 

Assuming that both systems are equally well designed, the higher pressure system will atomize a liquid better.
