I think my favorite update was the Spa Refresh, including fingernails. I love fingernails! I add them to almost all of my Sims, especially the females, but also some of the males.
I also liked Sims Sessions, but didn't care about the clothing you can "earn" from it. I rarely use T-shirts in the game, and when I do, it's always either plain, or something with rainbow. I don't like T-shirts with logos or writing on them, even in Simlish. I like the fact that you can still purchase the stage in buydebug (at least you COULD for a while; I hope they didn't remove that), and experience those concerts again. :) I'd never heard of any of the artists before, but I enjoyed the music in the game.
I love the Scared emotion, and have deliberately made some personal mods that take advantage of it. :)
I love the skins and hairstyles updates. I recently went back to playing Sims 3, and was appalled at the complete lack of variety in hairstyles for other races than Caucasian. There are almost no curly hairs at all, and fewer for men than for women. I had never noticed it before, when playing Sims 3, but I sure notice it now, after all the updates in Sims 4. You absolutely need CC in Sims 3 if you want more variety, which is sad.
I love ponds! I'm not that great at building with them, but I like that they're available. I've downloaded a few homes with them, and I love how they add to the curb appeal and interest of the lot.
I like the IDEA of scenarios, but haven't been too impressed with what we've had so far. I've seen some modded scenarios that look interesting, though, so at least having them gives modders more things to work with. :) I just wish they allowed a scenario to work with an existing household. Without that, they are far less interesting to me than they otherwise could be.
So far I don't care too much for Neighborhood Stories. They haven't had much of an impact in my games, other than being a nuisance. I use MCCC to add story progression to unplayed townies (so they'll at least, you know, have BABIES, and not remain sterile forever), which makes Neighborhood Stories less impactful for me, but the phone calls and texts I get from them are annoying. Like many others, I wish we had a toggle to turn them off. I've heard of players getting calls from townies for questions that would impact their own current characters, and it can sometimes be a bit baffling.
