What is your favourite way to play The Sims 4?

I spend about 80% on actual gameplay, 15% redesigning lots I've downloaded, and about 5% in CAS. I usually only go into CAS to change my one family's outfits or after the release of a new pack. Lately though I've been thinking about creating a bunch of sims and adding them to Not In World to hopefully get rid of some of the game generated townies.
