Lifestyles: how's your experience?

Lifestyles are definitely bugged in the sense that the game will assign a sim more than 3 lifestyles. And removing them only removes them from the sim info panel, it's still listed as active under the lifestyles button.
Personally, I know I'll turn them off in any further saves. They have too much impact on a sim's mood if you ask me (I'm the micomanaging control freak type of watcher).
While I appreciate the idea, it's too dominant in gameplay. Besides, it most of the time doesn't make sense.
I think it would have been more enjoyable if they had been interests, activities that sims naturally gravitate towards. Not something they crave so badly it ruins their whole day.
