| Kai's verdict | S-tier. Market leader with reason. Start here for serious video. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. S-tier if you self-host. The reason open-source image gen matters. | A-tier. Close second to Cursor. If $5/mo matters, start here. |
