Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
