Everywhere is better then the UK. Canada is fantastic (service is great too), America has some great bits. I love the Florida Keys and Seattle is great in Summer too. NY is just a bit too much for me, but shopping at Macy's etc at Christmas is good.
Have to admit, we're considering out options at the moment. We would have enough points for Aussie :-) , also looked at Hong Kong (property is expensive though).
Canada is too cold in winter for my liking, but others love it. Wouldn't know where to start with emigrating to the USA, plus it feels like one big dartboard target for enemies!
