Are you someone who has left their country of birth to move and settle somewhere else, or who is thinking of doing so in the future? What led you to take that decision, or what is making you consider it? What have your experiences been until now, and what do you expect and hope for in the future?
Italy would be a top choice for sure, anywhere on the Mediterranean would be ideal really. Wouldn’t be opposed to somewhere like Germany or Netherlands either.
Not EU but I’ve also considered trying to get a short term work visa in the UK and living there for a year or two. Honestly for no reason other than I love football and raves and those things are objectively better there than here.
I am currently making plans to leave the Mediterranean myself, so I feel obligated to recommend you to make a lot of research and think about it thoroughly before taking that decision. Coming to the Mediterranean can be a bliss or a nightmare depending on what is it that you do for a living.
