My first New Leaf town, I reset and reset and reset until I got the "perfect" town... the fruits I wanted, the grass shape I wanted, starting villagers I liked, a town hall I liked, and so on. But after a while... I got totally burned out on that town, because it was too perfect. So I reset, once, and picked 1 of the first 4 layouts that popped up. And honestly, I love it more than I ever liked the "perfect" town, because it has it's own character.
The two things that I do look for is the town tree in front of the town hall, and a starting fruit of pears, because I don't like pears at all and will eventually replant them all with other fruit.
