Really nice comparison. If I am to be honest, I'm more of an city guy after all, but it all depends. If I stay in the city for a few months, the I would love to escape on some island for a few weeks - just to not do anything and rest, swim and sightsee,
but after I do that for a bit I actually become bored of this lifestyle and I would love to do something more engaging. So I guess, that I prefer city over the island in the end - but to fulfil my existence I need both :P
