-the stairs bug fix
-children gardening (cooking might be good too, but I don't use it)
-ponds
-Fingernails (I don't use them very often, but it's nice to have the option now)
-Skintones, hair colors (especially "neutral" black)
-Bunk Beds
I never or only rarely use most of the other stuff, and don't personally care about one way or the other -- as long as I can turn them off. Some others I wish I had been given options to turn off. For example, I use very few base game BB items, so all those gazillion new swatches are just sitting there taking up space for me. I rarely use the Likes/Dislikes system for my played sims and wish fervently that I'd been given the option to turn it off for unplayed sims. I don't really care what preferences the game gives to pre-mades or randomly generated townies, but I HATE being forced to micromanage my own custom townies now. They already had their own story-purpose preferences in the first place. The game never fails to wreck that, turning them into just a bunch of other NPCs with new likes/dislikes that have no purpose or meaning to their actual stories. I don't use Neighborhood Stories, either. If the game had offered me an option to turn it off completely, I would have used that option. Instead, I now rely on the brilliant @83bienchen for a mod to do that for me.
Edited for clarity. Another word had mysteriously gone missing...
