I currently have the fairy tale themed city hall and train station since long ago.
Out of all of the themes I like the fairytale, Japanese, and modern theme, too bad i cannot have more NL towns for the time being.
For me, it's an even split between the Japanese theme and the Fairytale theme.
Both are just so cute!
Right now, my town matches the Japanese theme much more than the fairytale, but I'm looking for a second copy to make a Fairytale town soon
I like both the fairytale and Japanese train stations. However, my decision on which one to pick depends on which I believe will better complement the overall aesthetic of my town once I've completed decorating.
I love the color scheme of the fairytale buildings. They seem like a very unique blend when compared to the other styles, even if they don't fit my town's theme at all.
I personally just like the classic one, I think the other ones kinda stand out too much in my town for me so I just stuck to the original design, but I do genuinely like it most. If I had to pick out of specifically the upgrades, it would be the Japanese/Zen one, its such a nice design, I wish they would bring back customizing public buildings
