Medical research companies will naturally gravitate to a country where the medical industry is particularly profitable: for example in a country where citizens pay over the odds for healthcare due to disfunction. If this is the reason that the US spends the most on medical research, is that really something that qualifies as a valid variable for some definition of "best"?
