The intake charge is static and trapped behind a closed intake valve during the period when most fuel vaporization happens.  Would not big droplets of fuel be best?  The reason is the vaporization of larger droplets requires more energy and this results in a cooler and more dense intake charge.

A cooler denser charge is good, but if the big droplets don't vaporize, they don't burn. Consistent good cycles depend on consistency of the mix and give the most power.
