(I have all of the packs, but not all kits.)
Still playing Sims 4, though I also play a modded Sims 3. The Sims 4 toddlers and Sims 4 vampires are my favorite, and I have a hard time going back to Sims 1/Sims 2 at times because of Sims 4 and Sims 3 (with mods).
With Sims 4 (and Sims 3), I am still exploring all of the packs.
However, my most used packs so far (for gameplay, not just decorative B/B and CAS):
-Island Living, for the mermaids/merfolk!! I gotta have my merfolk. ??♂️??♀️ And the other water/beach/island activities, of course.
-Parenthood: for the values gameplay and bagging lunches, and parenting skills
-Toddlers: but, of course. They are very cute and independent/adaptable.
-Realm of Magic: spellcasters!
-Vampires: for the vampires, of course
-Get Together: Clubs system!
-Discover University: Working from home Education job
-Outdoor Retreat: vacation for family
-Dine Out: dining out, duh
-Spa Day: well, for spa and wellness of course
-Get to Work: retail businesses! (I missed Sims 2’s business pack.)
-Laundry Pack: laundry, of course
-Cottage Living: farm animals, crop growing, cross-stitching, etc
Knitty: knitting projects to sell/put on plopsy or create for sims or animals, etc
-Seasons: seasonal gameplay and holidays!
Get Famous: careers and fame stuff
I think I use a bit of everything for many packs.
The only packs I rarely touch upon were Eco Living (but my sister plays it), Strangerville, Cats & Dogs (but my sister plays it) and Tiny Living (but my sister plays it). ?
