I'm unsure whether I prefer winter or summer, honestly. I hate cold and having to wear a coat and boots and taking 2x more time to reach my destination, but I also hate too much heat and being all sticky and bugs and I have a love-hate relationship with the sun.
I guess the best season is autumn, where the temperature is more in the middle, and it's better than spring because there isn't as much mud and yuck because of all the melting snow. There's absolutely nothing to do outside in spring, and you never know how to dress up before going out because the temperature sometimes goes from -10C to 20C in one day
