Any downsides of living in Sweden?

I pretty much hear only good things about life in Sweden: good infrastructure, healthcare, education, social benefits, etc. Even the downsides of cold winters and social isolation that some mention don’t sound bad from my pov, I kind of like cold weather and being by myself. Are there actually any downsides besides that, since all I see online are only positives and it sounds like the almost perfect place to live in?
