Mostly pretty good, though i wish Jespar would sneak when I do at the Aged Man's Manor - he seemed fine with sneaking the rest of the time, so it was a bit weird that he didn't there (I know there's no NEED to sneak, but HE doesn't know that!)
Couple of points that stuck in my memory aside from that:
Calia, during the Star City sequence, was only managing to take one hit from virtually anything before she was crawling around (I used "getav health" because for some reason the mfg expanded info wasn't showing up, and it said she had 100).
A couple of times, Jespar/Calia got stuck in the sneak animation - wasn't an issue the first time with Calia, because we were somewhere with chairs (if an NPC gets stuck sneaking, and you can "command state" them, making them sit seems to fix it) but with Jespar and the other time with Calia, we were not anywhere that this was an option. This is a vanilla Skyrim issue, ofc, but I've only ever experienced it once or twice before in around 2,500 hours of Skyrim (and I usually have a follower or two with me) so it happening three times in one playthrough where there's probably less than, what, 20 hours where I've even got someone with me, and I wasn't sneaking all the time? Might be worth looking at.
I don't remember being able to command them last time, and I don't THINK they snuck when I did (although this was a year or two ago, my memory could be wrong), so if those are new, then hooray, because they're useful, if not, ignore me!
Oh, and I was playing on Adept mainly/switched to novice later on.
