Yeah I'd definitely recommend EU over US any day. So much more culture and stuff to check out in EU, plus you can go to different countries by train really easily. I'd highly recommend barcelona, paris, Deauville (in normandie, where the d-day beaches are), brussels, Bordeaux, Biarritz (at the border between france and spain), Cannes and Nice, Geneva, Amsterdam, Rome, Venice, Naples, Vienna, Copenhagen and Stockholm. Never been to Germany sorry.
