Why do you want to reset? We can't give you much of an opinion if we don't know why you're considering it.
In general, I think it's a good idea if you're unmotivated about your current town and would enjoy playing in a new town more. If you're very unsure, you could always try to play with your current town for a while longer. Unless you have a really bad map with lots of rocks, you can probably try to fix some of the issues with it and be creative. If you still hate the results you can reset, but it's easier to reset a town you dislike than to get back a town you liked but reset.

If your town is being upsetting and making it hard for you to enjoy the game, you probably should reset. What's making you unhappy about your town? Is it your map?
