As an European I can't say how well it compares to the US but The Netherlands (Amsterdam in particular) are an amazing place to move to.

I've left Italy a few months ago and moved to Amsterdam (studying and working), it's an amazing place, a massive change of settings for me. There are lots of startups, companies and opportunities for tech-minded people. Obviously, I repeat, my comparison is with Italy which, to be honest, is one of the worst places you'd want to found a startup in Europe.
