From Worldometers.info:
To make a fair comparison, population of UK is about seven times as much as population of Sweden, so Sweden peak 100 daily deaths is genuinely lower than the UK peak of 1,000.
Total deaths per million population is Sweden - 570 (sixth worst of all large countries) and UK - 686 (second worst, only Belgium is worse with 851).
It also appears that Sweden messed up old age care homes as badly as the UK did.
