Pretty sure it's much more generous than the UK for everyone except the well-off. In many cases the US managed to pay more than 100% of people's previous salaries in unemployment, structured to be most generous compared to their previous job for those with the least pay before, whereas furlough for those lucky enough to get it was capped at 75% and unemployment for those unlucky enough to lose their jobs entirely was barely boosted over the stingy standard payments. Unfortunately, trusted US publications like the New York Times mislead their readers about this for nakedly partisan reasons, just like they did with every other part of the US pandemic response and how it compared to the rest of the world.
