Apples, I wouldn't accept anything else for my main town. Had them in all my past games, IRL and their perfect version just looks so delicious!
My secondary town has Cherries, as they look better in Winter and once we hit Winter I'll keep it snow covered forever. Plus it makes for easy bells if I ever need.
Peaches....not too fond of them but whatever. On my 2nd town it is apples and I LOVE it! The perfect ones look so awesome, my whole town is literally covered in the trees lol
