Depends on your preferences. If you wish to have relatively large breasts, I'd use the new weighted BBB DRMA HGEC, LIGHTGuts body package. For faces, I'd use a race, like Blood Elves from Bella or the Ao Si or any new races you like. If you want the NPC"s to look better, use Natural faces, or any of the vanilla armor mod replacers, like Color Wheel's. Spend some time searching in the mod categories, and look at some YouTube videos that have the link in their description for the mods. I'd also ask unloaders in which mods can work together.
