The more you have weight to rotate to more torque you create, however this also means slower acceleration. A fine balance is always needed.

The steel bearings are more heavy to accelerate compared to the ceramic bearings and so there is some torque difference in favor for the steel bearing. However a little less acceleration.

Be aware that we are speaking about very little differences but always a large discussion about this.
My personal thought is that it is cheaper to change a steel main-bearing compared to a ceramic bearing and the overall performances of a steel bearing are as good as a ceramic one.
