Everyone's circumstances are so different.
It is hard to comment except from one's own perspective.
I lived in the USA for 5 years, worked in Oz for 3 months and visited Canada.
My opinion is that I would not go back to the States, Canada looked better than the USA but is still too similar and Oz looked very relaxed and the houses were so cheap as Iain pointed out.
The UK is almost as stressed out as the USA.
Oz is so far away though![]()
