Against the present Darkseid the doc would beat him alone. Against precrisis Darkseid they would both be owned, what was the super Wizard in Legion of SuperhErroes called. In thE great darkness saga he stole his power in a second. That same story he took over every Daxamite on Daxam teleported Daxam with his will to a yellow sun and unleashed them. Now he is a sad copy🙁
