In the U.S. obviously Florida. In Europe obviously Sweden, perhaps together with some countries in Eastern Europe.
Even if your ideal COVID strategy is "do nothing", TX and GA are doing better than FL
By what metric?
Cases and deaths per capita
Florida has an older population, so, all things equal, its deaths per capita would be higher. But, it was Georgia that initially did lead the charge on reopening (remember "Georgia's experiment in human sacrifice"?), along with Tennessee. I think South Dakota and Alaska were right there too, but they are such small states with rural populations that they influenced the culture less.
