"I found it interesting that you think of him" FWIW Holcomb was asked what kind of singer he was and said blues singer.

There was only one Sonny Boy Williamson. Because Sonny Boy was hugely popular and influential (e.g. harmonica became much more popular in blues music because of him), Rice Miller chose to be a local and eventually -- after Sonny Boy's death at a young age -- international imposter who didn't even bother to sound like Sonny Boy and lied that he was the "original" Sonny Boy when Sonny Boy came up.
