Lilycove for me. A big city with stuff to do and good surroundings is what I look for in a city. Big Contest Hall, Safari Zone just outside, the huge mall and many other things. There are a lot of people to talk to and it's a relaxing area once Team Aqua have been gotten rid of. Also, there is a sea to the right of it which just adds the beauty of the city. Plus, from the adjacent routes, you can catch some pretty amazing Pokemon; Staryu, Vulpix, Shuppet and the dozen you can get from Safari Zone.
