Shidake (Verdanturf) Town is too sleepy for my tastes. The locale has gorgeous flowers and all that greenery, but there's not much to do there unless you like Contests in Ruby/Sapphire, or the Battle Tent in Emerald.(rip petalburg and oldale)
Music-wise, Verdanturf is my favorite because I'm a sucker for pianos.
With design and aesthetic in mind I would side with Mossdeep because it's near the only ice area and ice is the best. However, I have this terrible fear of the ocean so my favorite after Mossdeep is Fortree, but I'm scared of heights too. So my favorite is Mossdeep, but I would want to live somewhere normal like Verdanturf or Rustboro.
