Is Philip Schaff an important voice in patristic studies?

Philip Schaff's anthologies of the Church Fathers are frequently referenced in online conversation due to their accessibility on newadvent and elsewhere, but my question is about Schaff as a patristic commentator. I am not aware of any impact he has had on the later study of the Fathers. Are his commentaries on the Fathers of any scholarly influence or value? God bless, Daniel
