Best US place to live? Too many choices. That's what is so awesome about the US. It is so big and built up everywhere that there are so many cool places to live. North, South, East and West - PLenty of diversity and a place for everyone.
Regarding Americans liking Brits. One of the few natinalities that don't crap on us incessantly. We kicked their butt for independance but since then we have been great mates. They appreciate it when the continentals periodically start a war and we come over to help out. I won't say we save their ass because the Brits are awesome fighters.
OK, I'll say it. Unlike the French who sh!t on us all the time even though we continually bail their ass out.
Aussie's like us too. They have been great friends over the years. My take is that most other countries are jealous and everyone likes to have a go at the guys on top. It's human nature. I don't lose sleep over it.
However - When you visit the US no matter what nationality the "average" American will treat you well and be nice to you. We like to be liked. Many Yanks are not worldly but that is as much about having a very complex domestic situation and a huge diverse country at home as it is about education.
And face it - Everyone in the world looks at the US as a way to increase their quality of life if they could only migrate there.
Oh and if you think that foreingers can't do well look at the median incomes by race. Asians rock in the US and immigration makes the US stronger.
