Spain had 14,8% excess mortality than in normal years, Germany had 2,4% less dead, Sweden had 3% more dead. These numbers are adjusted for demographic changes. Sweden now looks pretty solid as well as Spain regarding new cases.

Sure, if you just compare it to Norway and Finland, it is very true that Sweden has worse values, more than 3 times as many dead at minimum. But the answer if it was the correct or wrong choice will be answered after the current seasonal outbreak or in a few years.

edit: Just looked it up again, Spain and Sweden are currently leading with Kosovo for having the lowest case incidence in Europe. Gibraltar has the highest and everyone is vaccinated there. I remember the articles about Gibraltar being the first immune country. They now have cancelled many official events.
