Joe makes good classic R&B, but Kells is the king without a doubt - great classic r&b your parents can love, updated r&b with the 90's/00's sound, tugged out r&b, sex songs, inspirational joints, he produces his own shyt and HITS for others (maxwell's fortunate is a GOAT song of all time), he writes his music, dude even sounded nice (for that era) rapping. Even tho he fell off, he's still the KING. (same way MJB is still the Queen even tho she's not really making noise either)
