Immersion.
Though we have never had dragons flying around our sky's or other fantastical elements, I relate TES worlds to a medieval era and everyone wearing big pants is just wrong IMHO.
Body choice for me is a long story, and very much limited to the talents of our community members, and support for them. With Oblivion HGEC/EVE was the widest supported so for choice was the logical body mesh to go for. I loved Luchaires TGND female body, which just needed a HGEC compatible texture ... take your choice from those - But TGND was very limited in support from the Community because it did not have larger "attributes" variety. Not the authors problem, just a sad fact that the majority of any community are going to be attracted to more voluptuous forms.
Though it did come with all armour and clothing meshes to fit, Luchaire and Kalia put a heck of a lot of work into that. And the authors kind of burned out during the transition of TGND v1 custom armour and clothing to v2 TGND,
For Skyrim currently - My personal preference for female nvde body meshes is Prometheus. Basicly because it is standard mesh sized, does not need vanilla armour and clothing re-done to fit the body mesh and you can use your preference of body texture (so long as it is vanilla compatible, such as Navatseas textures which I use).
And it will be compatible with any armour/clothing created for vanilla female body meshes .. Which usually tend to be Lore friendly which suits me fine.
For the family .. Well they are going to be drawn to less immersive armour and clothing, which will need a more popular and supported body mesh ..
Which I think is going to be Dimon's UNP. Already UNP is having all armour and clothing converted by another modder Exeter who is doing a superb job of that, and also supported by Navatsea's vanilla / UNP body texture.
Though the family may be equally as happy with say Calientes body and choices made for it, its too clean and caters more for the eyecandy crowd.
I have three ladies in the house who like realism, but also want greater choice in the wardrobe department eventually for whatever role they wish to play.
Males - Even more limited, and probably will be for quite a while.
The last deciding factor is performance. All praise to those who import hugely complicated meshes and make them work in skyrim, and add huuuge body textures over them which make screenshots look fantastic .. However I like my NPCs to move fluidly too in a fight, not have to mortgage the house just to get new machines to run them ..
and more importantly leave enough system resources to be able to use other mods in game aswell as body mods.
So, yeah, I'm fussy
