I haven't got through a great many things yet, but so far so good. And I know I am going to love the rest of it too.
The world is stunning.
I have been enjoying the simplicity of seeing my sims relaxing in their house with no shoes on - how unnatural it always seemed to me to go about the house in shoes before this. I am adding the no shoe ability to all of my houses! (Shame I had to use a mod to take away the awful animation though).
I love all the build/buy and most of the CAS. The only build/buy item I would alter is the kitchen counters - I would have liked a 'full' version to go with the empty shelves, because we do not have much decor that will fit there. Or some extra pots, pans and plates decor ;) It's great to have more Winter clothing.
I like the small additions of choosing to eat with chopsticks if you want, and the little portable heater (I still wish they made the previous radiator useable though).
