They are also closest to the real socialism, no Soviet country got even close to what they are doing - and I am saying that as a person coming from a former soviet republic.
The difference however, is that they willingly(and democratically) choose to provide all those social benefits.
Good for them.
This is just plain wrong. The means of production in Sweden have always been held in private hands, the one attempt to change this ended in spectacular failure. The big exception would be LKAB which is the owner of the iron ore mines in northern Sweden. A country where private equity companies owns schools is not socialist.
There is a large public sector in the Nordic countries but this is run off the taxes from these successful capitalist companies and their employees. So a better name would be welfare capitalism, not socialism.
