Rema Choshen Mishpat 14:1 Are all Rabbis Created Equal?

Concerning Dayyanim:

«If two Hachamim have equal s'micha - we go after the greater - "the Gadol"»

So if their objective ranking is the same how is it thay one can be greater?

• Are all Rabbis created equal?
• Are all Dayyanim created equal?

Or has the "subjective" ranking always been a factor in Beth Din?
