I've got the Sony/Columbia set. The sound is ok, certainly better than what Sony was doing 15 years ago when they first started reissuing music from the 1920s and 30s on CD. This set is good for someone like me, who's not intimately familiar with Southern white music of the period, as it has one disk of the "best" of Charley Poole and two disks of Poole's recordings placed among those of his influences and those who he influenced, so you get a picture of where he stood in the history of the genre.
