I really wanted orange as native fruit. I ofcourse had apples first, like with NL. But I like apples least so I really wanted an Orange island. Very happy with my oranges and find it very cool that it gets mentioned in game I really hoped there would be lemons but sadly there aren't
Personally I like oranges, apples and pears! I'm biased towards oranges because that's what I have on my main island. My second island has peaches, which I'm not really a fan of, so I think I'm going to plant a bunch of apple trees instead.
Since they're all easy to get by in NH and there's no perfect fruit - please note apples, pears & peaches makes your villagers sometimes carry a green fruit juice, while the cherries net you a red/pink drink & oranges of course orange juice.
The latter two are most aesthetically pleasing in my opinion!
So cherries are my favorite in NH - if perfect fruits returned it'd definitely be apples.
I think pears are my favorite, mostly because they've been haunting me in basically every town I've made since my very first one on AC:GCN back in 2008 lol. I also love the peaches and cherries because they're very aesthetically pleasing :3
