They are equal but just in a different format. Grahdens is more defensive while Owen is more offensive. It's probably based on their omni lore ( which I have not seen yet this is just speculation). Grahdens most likely wanted to fight the gods so he began training young summoners to back him up ( If you have noticed, most of the time Grahdens never goes up against anything unless there is someone backing him up). While Owen decided to kill demons by going solo (He took on Shusui by himself and won. I still don't understand why the hall didn't send him to fight the four fallen gods).
