Kai's verdictA-tier for creators training custom looks. B-tier for general use.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Still early. Manus is more flexible for less money.
