Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
