I've just got back from 18 months of travelling and now looking for a job, a flat and to settle down somewhere.
It sounds like you're looking for a job that has equal opportunities everywhere. Some occupations have better opportunities for advancement in some places than others (e.g. London vs. Manchester). Would your future career prospects be better in one place or the other or does it not matter?
As an aside I once knew an aspiring actor here in New York who was originally from Montreal (Canada). He once commented that he was so glad that he went to English language schools as a boy rather than French language schools because if he hadn't then he'd still be there (implying that opportunities in theater are much better in New York than in Montreal). It doesn't sound like you're looking for a job in theater, but you get the idea.
So I suggest that you bring your future career aspirations into the reckoning as well and see where your opportunites are best served.
