One connector between the battery and the ESC.. meaning one male - female pair, is the simplest thus the best way to go.

Yes it is the simplest, but if the batteries arrive with the wrong connector ( as is always the case in this hobby ) "simple" is wiring up a new adaptor so you do not have to tinker with rewiring or miswiring the packs.
Do it once per connector type and forget about it, instead of having to tackle each pack or ESC separately.
