The benefit of SSRs over mechanical means of switching are the prolonged service life provided by SSR. No moving items and no electric arching allows SSRs to be switched rapidly and for more cycles.
Depending on the switching rate an EMR (electromechanical relay) could quickly wear out, especially in our usage for temperature control.
EMRs and contactors have great purpose but rapid, repeated switching just isn't their thing.
