Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. S-tier if you self-host. The reason open-source image gen matters.
