I'm also from Portugal and know our stats well. We're not doing well, and haven't really done all that well in the past either. Comparing Sweden to their 3 immediate neighbors makes a lot more sense.
There are so many different variables between countries, even neighbour ones, that it makes no sense.
Sweden old people homes are (from what I read) basically glorified death waiting rooms. People don't stay in them long (months vs years in other places). Also people movements during the high 'season' of covid spread is different (Students do different things in spring break between countries). etc etc etc etc.
Not saying Norway or whatnot is not doing better, just we don't really know. (Same as saying Portugal is doing great because look at it's neighbour spain kind of deal)
But we do, excess deaths have all causes integrated. Comparing to the Nordic neighbors makes sense because they have more similarities than comparing to Portugal but feel free to compare to all the countries in that website. Sweden is worse than most.
