Here's a breakdown for Sweden...
The Good:
1. The girls (and guys) absolutely love Americans. I haven't seen anything like it. I feel like half of the Swedes I've met have stayed in the US for a while and even those who lived in some bumfuck place like Ohio or Arkansas have warm thoughts about our country. The moment they find out I'm from the USA, their eyes light up and they start asking me a bunch of questions.
Of course I play up the angle by talking about Apple, McDonalds, Starbucks, hamburgers, and pizza. I've been to a lot of places, but I think Swedes are tops in liking the USA. There was a thread on the forum where a black guy said Swedish girls love American brothers. He was half right: Swedes love Americans, period.
2. The girls are friendly. You get some rudeness occasionally from anti-social girls but by and far most of my interactions have been extremely pleasant. The girls are not militant feminists like in Denmark. I'm not getting shit tested or otherwise having interactions that left me bitter or angry. I got a similar vibe from Finnish girls as well.
The Bad:
1. Expensive. It's not as expensive as Denmark, but almost so. I don't want to look at my online banking because of the absurd amounts of money I'm dropping for not really doing anything.
2. The average quality is very low. Don't let Swedish Bikini Team fool you. The typical Swedish girl is overweight, doesn't know how to dress, masculine (not as bad as Danish girls though), doesn't know how to flirt, and has a strong man jaw. They are tatted and pierced. I feel bad hating on them since they really are nice, but this is what it is.
You have the top tier which is very pretty but inaccessible, the occasional 7 who is surrounded by her beta orbiters, and then a whole bunch of frumpy and dumpy chicks rated 6 and below who think it's cool to wear Converse day or night. The Converse shoes really are annoying me, since girls wear it with any type of outfit. Up to 50% of girls in a bar will have these on.
3. The nightlife logistics are among the worst I've seen. It may be worse than Argentina and Colombia. You have tons of bars where people sit down in their groups and then you have snobby and expensive clubs where everywhere seems to know each other. Social circle is king in Sweden so no matter where a girl is, she will know at least five people in the club, mostly guys. The guys won't directly block you but they take up the girls' attention.
4. Day game is average. Not easier than anywhere else and typical for Scandinavia, though it's often better than night game. While you're still dealing with typical Scandinavian shyness, being American propels you over the hump to to get day numbers.
My true feelings about a country usually come after I get the flag. In Poland, the Baltics, Ukraine, and even Finland, I still went out hard after capturing the flag to see what else I could snag, but in Sweden I was ready to hang it up and just dive back into work.
Besides casual day gaming, I didn't care for spending boatloads of money to deal with average girls in clubs where everyone knows each other. Iceland and Finland were better in that respect.
In the end, the hype surrounding Sweden was totally unwarranted. Finland was better, in both quality and ease of banging.
I guess there is a reason why you see so many Swedish guys in South America trying to get with the girls there.
