As a Long Islander, I consider myself to be a New Yorker by default, and I would chose NYC every time. I am not a great fan of London, I have lived there on two long term ocassions (about six months each time) and I always have come back to Manchester. IMO and this is JUST FROM MY EXPERIENCE FROM MY OWN LIFE EXPERIENCES the people in London were never friendly, nor were they looking to meet new people, Manchester, well, thats a different kettle of fish entirely. I love going home to visit NYC, and I could spend weeks there, when ever I have to go down to London for anything, I can feel the Northwest calling me back. London and NYC have similar feels, but completely different types of people.
