If you're not happy with your town map, I'd say yes you should restart. If you're okay with your town map (and town name), I'd demolish everything and let every villager move and try to start from scratch. Though you'd have to kick away all the paths and maybe fine new ones.
Whether you reset or not you should start looking at some villagers that you actually like and try to adopt the from camp or this site!
I'm definitely enjoying my new town, so glad I restarted!
Unless you have the time and energy to make changes I would say no, but if you are incredibly unhappy with everything i would say go do it. before resetting i would recommend either giving away your stuff you already have, selling it, or ask someone to store it for you! anyways good luck //
