Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for model-shopping. I use this for every prototype before committing.
