They might be almost as effective when both are working on their optimum, but a steel brake would not be as predictable as a carbon ditto over a race distance. Carbon brakes, when they are heated up, will stay remarkably consistent until they break.
the problem is as we all well know how long do you really think it would be if steel was reintroduced before the teams developed them to a point when there was no difference?
I feel certain it would be weeks before they had steel disks working reliably and consistently into the 1000 degree range or developed a way to ensure they managed the envelope so their brakes were consistent.
The bottom line IMHO is that steel disks are not the way forward they would at best just put the teams back maybe a few months at best and then we would be right back where we are at right now.
edit add
So if they were to go the brake route the only realistic option would be yet more spec parts on F1 cars this time spec braking systems including disks, pads, callipers etc.
call me selfish but i dont want more spec parts in F1.
