What English speaking country would you most like to live in?
In short, all other things being equal, what country would you like to live in? Forget family ties, job security and all that jazz.
Personally, I'd probably either pick Canada or Australia. Australia is beautiful, and I really like the culture from what I've seen, but I don't do well with heat. Canada would fix that problem. Besides that, I've heard it has a pretty good Internet infrastructure, especially compared to Australia. On top of that, I'd be relatively close to the US, so visits and/or contraband are more feasible.
