I was always talking about who was stronger.But anyway i never got the feeling that were talking about who's more skilled or a better fighter. Thats CLEARY Diana which is very obvious during the whole fight. MC is HARD CARRIED by his nephilim powers the whole time, plenty of people are more skilled fighters.
Diana is clearly stronger and the mc was mostly just relying on his regen powers to be able to stay in the fight at all.
I just don't consider regen the same as being more powerful. I'm basically thinking in terms of dps.
