As a foreigner, I think the U.K is better for me for some reasons...
1 - There are lots of Beautiful landmarks like old castles and natural places for a medieval buff like me and more WW2 historical sites than in the US, which I am very interested in.
2 - Healthcare there is Free.
3 - Its rather safe in there; you will not have to worry about mad gunmen whilst watching Batman... or Studying in your school...
4 - The countrysides are very remote and peaceful for peace loving people like me.
However, I like the US too you know, especially the video games they make and the American Football and don't forget, E3 is mostly held in the US. But still, if given a chance for a tour, I would rather go to Europe...
