Hmm, i use Aranea Ienith but not in a sneaky fashion
Any follower that is skilled at light armor and sneak should be fine (also give them muffle enchanted piece of equipment). Followers should preferably be non-mage, as casting spells will attract enemies and blow your cover. Complete list of followers and their descriptions here
If you have any more questions don't hesitate to ask Thanks for the support, cheers!
