I prefer the USB port to be on the bottom, but very few phones (at least in the smartphone era) even tried to move the USB port. Headphone jacks were frequently on top. I like the USB port on the bottom in the center so it can sit on a stand with a cutout in the center (which are pretty common).
Doesn’t really matter as long as the jack exists in the first place.
Same for charging port?
