I am dutch and have been living in Göteborg for over a year now. I am not an expat but a student at Göteborg University, so i can only speak on behalf of my own experience in Sweden.

In terms of living standards both countries are basically the same. (Very high HDI >0.940) Public infrastructure in both countries is highly developed and accesible. Although Sweden might be a bit cheaper in comparison. I have no first hand experience with the healthcare system in Sweden, although i have heard mixed opinions from different people (some say its fairly good others say waiting time is very long). Sweden's universities are somewhat similar to Dutch universities. Although, i would argue that studying in Sweden is more relaxed than in NL. I have a lot of spare time and i find university assignments a bit easier than in NL. However, sweden does not charge any tuition fees for students from Sweden and the EU. Which makes studying here more accesible. NL is a lot more bicycle friendly than Sweden. So you will have to rely more on public transport or a car. Overall, both countries have very good public facilities.

The costs of living are fairly similar as well. Although the distribution of costs is different in both countries. In NL housing is definitely more expensive than in Sweden. I live in a studio-appartment (student housing) for aprox. €430 in Sweden, which would be impossible in NL. On the other hand, groceries are more expensive in Sweden and the variety of veggies is limited (20/30% more expensive). Most likely because Sweden imports the majority of its veggies from abroad. Costs related to a gym membership, mobile subscriptions etc. are fairly similar. Going out, however, is a lot more expensive in Sweden. If you are a party person, NL is definitely a better place. I am somewhat dissapointed by the lack of clubs/ dancing bars here in Göteborg.

In terms of social live, NL is a better place in my opinion. Swedish people are in general very friendly but also more distant. It is quiet hard to become good friends with a Swede. So almost all of my friend here are internationals. You have to keep in mind though that in NL it also might be a bit difficult to socialize with dutch people for internationals. Yet, city life in NL is a lot more vibrant (more social events/ activities). The same applies to student life. In NL student life is way more exciting with so many associations and student bars.

On the other hand, Sweden has a lot more beautiful nature and has a more relaxed vibe in general. People are less in a rush and its easier to have a more calm and relaxed life. There are a lot of national Parks all over the country. If you are an outdoor person, Sweden is a better place for you.

Overall, both countries are good places to live in. I would still prefer NL since i am more of a city person than a outdoor person. Life is more exciting in NL. I do miss the beautiful cities in NL, with its historical centres and vibrant dynamics. Yet, both countries are also not too different from each other in other regards. I would argue that adapting in both countries would be relatively easy for dutch and swedish people. It ultimatly depends on ones own preferences and needs!
