Both really good but I warm to Kassandra more. While in Odyssey they may not have done the best by the character, as an individual I just love what they've created right down the hairstyle, She comes across very humanistic and appealing personality. I think it's a great achievement in character creation. They were on a roll with Bayek Reda and then Kass, was surprising at the time how good Origins was by Ubisoft. I'm not seeing the same quality in Valhalla.
When I boot up Unity it's for Paris, Origins it's Egypt, Odyssey it's for Kassandra
