That’s a bit hard to directly measure as the USSR was focused on production, rather than maintaining a crumbling Empire like the UK was, so measuring GDP in both countries is difficult (state-driven economies also have difficulty with tracking GDP). We can look at increases in metrics and access to goods, though, which led to a doubling in life expectancy for Soviet citizens ans dramatic poverty reductions (outside of wartime).
