Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for realtime. If latency matters more than voice catalog, start here.	A-tier for creators training custom looks. B-tier for general use.	A-tier if you already pay Gemini. B-tier standalone.
