exactly jb is the most talented as singer but his human side is too involved in his career either with his loss of motivation or his excess of loyalty lol strange to say but the guy is too loyal even at house level 90 per cent of employees have been around for 30 years almost
you gotta be gossiped hard on or do something which really pissed him off to be sidelined
while nsone is ruthless(sometimes too much) his group,his reputation of being a " star maker"will always go above any musician's opinion of destiny in the group or whatever and like you say nsone is a complete artist nsone became a singer after being on drums,mbonda,piano at church,bass and rythm while jb had always been limited to singing role,notice how funnily enough those who some people see as the worst singer of clan wenge( nsone and adolphe) are by far the best in quick poaching of talents
which is why wenge was a perfect puzzle,each of them had their assets and their limits and they completemented each other
even in the way their group is ruled,their group were at their best or close when werra had a mini jb to complement,and jb a guy who did werra's role
