Being old, and just having watched (again, after many years) some of the now restored and remastered installments of the Rathbone-Bruce series I must aver that for me it was Basil Rathbone, although his pairing with Bruce's caricaturesque take on Watson was a bit of a flaw, I believe. It allowed Rathbone, however, to appear at all times superior and masterly, which is what he did best. Also, with the possible exception of The Scarlet Claw (1944), the direction, writing and production values of these B-film series left something to be desired. I enjoyed the care taken by Greanada TV to produce the Jeremy Brett episodes, but I don't like his characterization of Holmes, as I find his ambiguous and neurotic Sherlock irritating and overacted.
