A farming pack caters to rustic living, eco living, historical gameplay, maybe rich sims too if we get horses etc. Doesn't have much use for city sims and only gardeners would likely find a use in suburbia.
Tropical vacation is nice, but how often do you send sims on holiday? 0-2 times per generation most of the time for me and not normally for more than a few days. They've already said that older worlds aren't backwards compatible if we ever get swimmable oceans, so most ocean based activities wouldn't be transferable to general gameplay.
Supernaturals is the most versatile for me. New lifestates bring new ways to live all types of lives, from a PlantSim environmental activist, to a Vampire politician, to a Witch doctor healing the sick with magic.
