Engineering graduate - US vs Europe

[Aresius]

I apologize if this has been discussed before, I didn't find anything.

I'll make it short:
1. I have dual citizenship (US/EU), have spent most of my life in Europe (UK) but came to the US for college. I am 22. As a whole, I relate better to europeans and the way of life there.
2. Have a B.S.E.E. and currently pursuing a M.S. in pulsed power.
3. Previously denied interim security clearance in the US after accepting a job offer at a defense contractor (hence why I decided to advance my education) - the issue is likely mitigated at this point.

I am curious as to the benefits (if any) of moving back to europe and pursuing an engineering career there. The field I'm in will likely place me in the defense sector. Are US STEM graduates sought after in europe? How does the pay compare? What is the level of innovation and research compared to the US? Political atmosphere and how it affects scientific progress and job markets?

I'd love to hear experiences from current professionals in both continents. Thanks!

Depending on level of clearance I would guess that other issues- mainly you having never lived significant time in the US outside of college- would come up in your clearance process as well.
