Perhaps we should investigate this topic with greater depth!
I do not remember anyone bringing up the question here in the Northern Hemisphere until now.
They say immigration brings in fresh ideas, and
now I believe it!"

First, we should define "greater than" for the purpose of this question. Just off the top of my head:

Paternity:
Bach fathered 21 children
Jackson has fathered 3

Endurance:
Bach was famous during his lifetime,
then became obscure, and was again
remembered in our time!
Jackson has only lived in our time.

Sales:
I don't know much about their relative sales.
I have bought a couple of tapes with Bach
and other artists together.

Musicality:
Bach wrote more notes than Jackson.

Value to society:
Bach helped the Catholic church regain its aura
of decency, which it had lost by little foibles like selling chicken bones as if they were relics of the saints. The church was undecided or divided about whether to back the Nazis
during our parents' generation.
Jackson helped the Catholic church regain its aura of decency by being accused of doing what
some of the priests were accused of doing. Just
being accused can be such a service! He also
helped promote the idea of artistic diversity
by being alternately a lover AND a fighter.

Welcome to Square One. Where am I?
