I think JBJ is better. His prime years were out of reach on Richie's part. But RS has that passion and tone that JBJ didn't have. He is great on stage especially on 1995 tour where he went nuts on most of the shows. But JBJ proving that he can still do it back on the LH tour down to the GH tour pretty much ended the debate for me. Add up his wide vocal range and then this debate is a no brainer IMHO
