The EU, because us Europeans are more civilized and show more restraint than you Americans. Basically, we've been around longer - we know how things work (we've already made our mistakes), and our solution to most problems is not "lets blow it up". Admittedly, the UK sided with America in the Iraq war, but the UK is unfortunately more US than European.
Also our welfare, economic and domestic policies and systems are fairer and more effective than yours. We don't have a national debt of $7 Trillion, we don't have homeless people dying on the streets, we have free health and education, and we don't have a society where half the black population are behind bars.
