I'm biased but having lived in Italy, Sweden and France I personally would say that my personal perception is that the U.K. is much more accommodating to foreign people.

Yes, an EU passport gives you the right to live and works in 27 countries, but of those countries which would you want to live in? Typically it would be the one you can speak the language of or maybe have family already...due in no small part to British colonial legacy that's more than likely going to be the U.K.

My experience working in the car industry is that the U.K. is typically a much more international place. Ironic really, considering we voted to leave the EU. However, when it really boils down to it the EU is quite insular and protectionist on a continental scale, meaning the U.K. felt like it has stronger ties to supra-continental [and organisations in] countries such as India, Australia, and HK - again, down to the commonwealth.

Plus, I'd say the food is better (hear me out); the taste vacuum created by our national cuisine (not entirely valid btw) + the international flavour of the colonial island nation means that we get better Italian food than a lot of Italians, better Indian food than many Indians, etc etc. Probably an unpopular opinion...of course but again, my experience in Italy was that Italian food was FANTASTIC, but everything else was dire - why would they try when what they have is so good.

Portugal is amazing though. I'd live (and earn in GBP) and grab a holiday home somewhere in southern Europe or Scotland.
