Try to sample them a bit, the coming festival season is an ideal excuse.

Any city is capable of becoming home (just look how many people call any given place home) but only you can tell whether somewhere can be home for YOU.

If you would express a few preferences we could probably make a few "I would avoid/consider xxx" suggestions, but at a time when personal development is at full steam you are likely to find that your taste will also develop, and not always in the way you might expect.

I think you have the right idea in moving out of the SW, I'm sure that it is lovely, but so is a lot of the rest and you will never have a better chance to try it. What about overseas, or is that too big a step/ruled out by other considerations?
