I love all three. Some days, Freddie, others--BB or Albert. Don't forget old Earl King, and Willie. Not in the same league as the big 3, but did some good stuff as well.
Probably most partial to Freddie cause of my younger days in Austin when he was at the Armadillo every month.
Gosh. I don't know! I LOVE Albert's licks, and his attitude, but B.B. does more with one note than probably anybody ever. Powerful stuff.... Freddie was great in his own rite.
I guess it's like asking which is better: Ice, Water, or vapor?
