"best" healthcare system is a meaningless statement, unless you define what is meant by best.
It would appear that in 2022 UK did not even make the top 10

Of the top 10, it would be interesting to know how many (if any) use a UK like model (I have no idea of the answer).
I do have some personal experience (anecdotal of course, but, I suppose my anecdotal evidence is a s bad, or, good, as yours) of two of the healthcare systems in the list (French and Spanish), as well, of course, our own UK system.
