I don't think the "greatest" there is linked to "the princes of the Noldor" - it is referring to Maeglin being the greatest "save one in the most renowned of their lands" - the greatest inhabitant of Gondolin save Tuor (obviously excluding the King), playing up Maeglin's competition with Tuor and his desire to have Idril.
