I tend to play the culinary career a lot, because it works well with my tendency to give sims the Natural Cook trait, plus I like careers that don't have promotion metrics like "reports/stories written" or "meetings held" and stuff like that, because I always end up falling behind on those. Also, the reward for topping the culinary career track (the most epic fridge EVER) is pretty sweet, so especially for my legacy families, I like knocking that career out of the way near the beginning, so everyone gets the benefit of the Epic Fridge. I also like the science career for its similar "only mood/skill/relationship based" metrics for promotions.
