My town hall is surrounded by all the different types of fruit, and the rest of the trees everywhere else are perfect cherries. I think they are the most colourful of the perfect fruits, and match my Rainbow-themed town.
All my towns only have one of each type of regular fruit. The rest are perfect, cedars, sampling and one bell tree.
One town has a few lemon trees for color behind two villagers houses.
No but I'll probably have cut down some normal fruit trees at one point. All other fruit doesn't look as pretty than the perfect version of your native fruit, and most certainly, bell trees. I plan on having lots of bell trees later in the future.
