My favorite has got to be peaches (Though I've never had them as my native fruit, figures) They look like little butts on cute little butt trees.
I love how pretty the apples are, and oranges are pretty cool too.
Anyways, My current town has pears as the native fruit, and I've been dealing with them. I don't mind them all that much, even though pears seem to be the most disliked out of them all. Perfect Pears look cool in the trees during the summer!
I have a special attachment to pears, just because that was my town's native fruit back in Wild World for the DS, which was my first Animal Crossing game.
Peaches for me and I planted one by my house in my town. Never had a town fruit that was peaches yet. My town fruit are cherries and I like how perfect cherries look too.
My favorite perfect fruit is probably the perfect apple, which is ironic considering it's the only one I don't have in one of my towns. The perfect apples just look so nice and glossy.
My main horror town has pears, which is kind of unfortunate since I really don't like pears very much in real life. That said, the golden color of the perfect pear does look nice.
My all-bird town has peaches, and they barely look much different compared to the regular peaches.
My magic/circus town has cherries and they're perhaps the least visually striking of all of the perfect fruits. But eh, I liked the town layout and a number of the starting villagers so it works for me.
Finally, my themeless town has perfect oranges. They certainly stand out with their distinct shape but I honestly just think they look kind of ugly.
If I were to replace any of them it would be the oranges, but even though it's a themeless town I've put a lot of time and work into it over the years so I don't care enough to restart just to have perfect apples. Maybe I'll try for apples to be my town fruit in the next installment in the series.
I like pears the best. It was the native fruit to my very first ACNL town before I reset. I got apples and peaches now in my two towns and they are nice too. I don't like the way perfect cherries or oranges look.
