I have far too many OCs to answer for all of them but I'll do a few:
• Rachel likes autumn the most! Summer is great because she gets to dress a little sluttier, but the sun is not kind to her pale skin.
• Dinky prefers the winter, she grows a lot of fur that requires a lot of shaving in the summer.
• Ela much prefers the summer; she gets embarassed by the extra weight snow nymphs accumilate during the cold months.
• Sunshine (ironically) likes the winter, as the nights are longer and the cold never bothered her anyway.
• Una loves all the new growth of spring.
