I can tolerate warm better than cold, so I'd vote summer is better than winter. Hiking, cycling is better when the weather is friendly and warm and days are longer than nights. Besides, I always prefer less clothing. Nature is beautiful from spring to autumn, in winter it's bleak.
I envy those people who move south for winter every year. A mild, perpetuated summer would be heaven to me...
