I own all the packs.
It's a bit cheating to say Seasons is the best because weather and seasons should honestly be in the base game but I still think it's a must to own it. Holidays are also fun to celebrate, and it gives you hot weather and cold weather outfits which are very neat.
Least favorite by far is Journey to Batuu. It's ridiculously, incredibly self-contained and I hate feeling like I'm being advertised Star Wars when I see it, the prior Star Wars CAS content was already bad enough. You can't even do cool stuff on Batuu too, like making your Wizards and Vampires do all of their cool powers and whatever. The only thing going for it is it has nice build/buy stuff but guess what? So does every pack that has build/buy content.
Eco Lifestyle ranks up there solely because of its extremely disruptive, irritating, and buggy NAPS system.
