Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
