I remember in my resetting frenzy stage of playing New Leaf that I would always favour Apples, I think mostly because of the perfect apples being particularly pretty
I voted for cherry because I think they're the cutest!! I also love cherry flavor in general, and I love the way the perfect cherry looks.. Never did get a town with that as the main fruit though.
Apple because it was my starter fruit and I love the way perfect apples look. For the longest time it was the only fruit that existed in my new-to-AC world.
