Is it better to go to Japan or Australia, Canada and New Zealand?

Considering the cost performance and other aspects, going to Canada and Japan should be the wisest choice. Australia's tuition is expensive and the environment is unfriendly; There are only one or two good universities in New Zealand, and the choice is too small; The best choice should be Canada (open tuition, good reputation with universities in Britain and Australia, good immigration and absolutely good social security).
