I'm relatively neutral because I like the world & Cas/BB for EL and I think Snowy Escape might need more to do but I should play with it more before making a full judgement on it. I prefer the theme of Snowy Escape and it has more features that actually interest me but EL has a quirky character that I like. I think the modern eco-style of EL does add to my game. On the other hand, while I said that I actually want more to do in SE, it does still have a lot and it is fun.
Maybe my opinion will change when I play SE more but I think SE actually needs something more, like a culture skill or some added feature since the shrine was replaced. I like that EL has friends and neighbors visiting. It's just that with SE, I've sent a few sims and they've stayed in the beautiful houses. They've learned some winter sports, eaten the food and gone to the onsen but then I end up saying, "Now what?" I sent one to the bar and it was a bit boring. I know they put a lot into the vending machines but otherwise the bar felt like it could have been anywhere.
I think Jungle Adventure did a good job of mixing culture, different ways to spend time and optional challenges. I might get into Mt. Komorebi more when I play it more and when I send my cross-cultural family there.
