To the previous comment, yes, both of the rings earned through the vampire quest (Erudite and Beast) remain effective even while not in Vampire Lord form. It is understandable that this often gets confused, as this in-game description on the Ring of the Beast claims "Claw damage," leading players to assume the buff did not apply to normal unarmed combat, when in truth it does. So to clearly answer your question, Ring of the Erudite is better than an enchanted ring by quite a bit.
