It depends what you want.
England is better, in my opinion, in music, and culture whereas the US is way better in entertainment like theme parks, things to do, and I prefer US food much better.
I feel much better walking around in the US than in England where there is a great deal of racism (sorry but it's the truth)
On the other hand, the UK is literature rich and the countryside is very beautiful, calm and refreshing.
There is more violence and the crime rate in the US is staggering compared to the UK where not even the local cop has a side arm.
BBC is way better than CNN where since it is commercial-free and whose headlines cover other countries that CNN usually doesn't and in depth.
The UK is safer!
I believe Brits are more educated in general - referring to manners, but less tolerant. The US is much more liberal and boast more freedom in all areas.
Education wise, I much prefer the rigid UK Secondary School system than the rather laid back High School. However in higher education the US has more money to reinvest in their institutions.
Some people, like TIME Magazine say Harvard is better than Cambridge University... That's a tough one. I believe they are the same or Cambridge more prestigious. I mean 800+ years old where Sir Isaac Newton was a student!!!
I love more British sports, i.e. Association Football than American Football and Rugby than Baseball.
Finally, I prefer the UK since it is in Europe and Europe is fun, fun, fun.
I hope I have not offended any US or UK citizens, whom I love. I go to both countries. I love both US and UK music, especially from the 80's.
