i personally think there are hot girls everyway. swedish guys will consider non swedes hotter etc. imo, humans will almost desire something they dont have.
Every country has beautiful girls, but people I've met often say Stockholm is nice. I never really thought about too much and don't have much experience from other countries - but I do agree there are a lot of pretty swedish women. Many of them are brats and seem to be drawn to douchebags, but I guess that's the same wherever you go, right?
Although a true Englishman would say that Great Britain is not part of Europe, I would say my favorite European babes are from the British Isles. (English, Scottish, Irish and Welsh)
