I like winter and it suits my island a lot more than the other seasons imo. I like the ethereal and serene vibe it gives everything and the pink camellias I have planted around my island look so much prettier in the snow as well.
I loved experiencing Toy Day and New Year's in-game, and the snow made it seem all the more magical. I was even sorry to see it go in the Northern Hemisphere, but all of the Animal Crossing seasons bring something fun and unique to the table so it wasn't all bad!
The only thing I wasn't a fan of, was how the season made some of the in-game paths look so drab and washed out. I actually switched out the brick path for the terracotta path on my island because it was bugging me so much.
