Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
