If you are saying that both Jesus and God can be called “God”, but that God is superior to Jesus in knowledge (and power and eternity) then that’s actually what JWs believe, not Trinitarians.
Jesus and the Father both (tho separate beings) are called God by the Trinitarians. "God" is a title. The Father is clearly superior in knowledge and the head of the Son, Jesus per the scriptures (Catholic and protestant). Yet the Son retains the title of God.
As I said somewhere in another thread, the teachings of JW and Trinitarians are not as different as they may first appear to be.
