My favorite non-occult packs are Seasons and City Living. I also use Get Together quite a bit. These are all older so you are likely to find them on sale if you don't mind waiting a bit.
Get Famous is fun, but it can take a while to get used to the fame system and celebrities can be intrusive (imho celebrities are more intrusive than any occult). I waited to get this one until I'd been playing TS4 for a couple of years and felt like I was ready for my game to get more complicated. I'm still waiting on Parenthood and Vampires for that reason-- I'm not ready for my game to get more complicated again yet, and both those packs seem like they introduce a lot of complications.
