In my experience CBBE has more slutty clothes but more customization with the body itself while UNP has more sensible clothes and has built in compatibility with Immersive Armors. For armor and eyes, it doesn’t really matter since CBBE doesn’t add/replace any files for either. If you are installing other CBBE-related mods that alter or replace parts of that, then logically you want CBBE installed first. CBBE is a body replacer so it replaces the vanilla female body meshes and textures.
