Wepons for demeter

I was wondering which weapons are better for Demeter, Deshret or Mace, I already have the Mace upgraded to the mk1 12 and they Good wepons, but now that I'm thinking of upgrading the weapons and I see that I have 3 of those other weapons, I don't know which ones are really better since I haven't tried those but in the tierlist it appears as one tier up. I'm asking because only the Mowgan ones appear in the Simplified Robot guide and I don't really have any of those xd
