remember: women in country X usually find FOREIGN men hot, not natives. polish dudes have a really, really tough time with polish chicks visited there a lot when i worked in london, there were a ton of hotties but they all wanted english/american/european boys not poles.
dutch/swedish/norway is a good bet, you have enough countries around you that will find you sexy, you will basically be healthy and have good genes, and being white is a positive anywhere you go. italian and spanish men have it pretty good too, although their job situations usually suck balls and a lot tend to be mamas boys.
worst would be asian or african or south american, chances are you won't even reach 18 and even if you do you'll most likely be poor for your entire life
