Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier for solo + free. The best free option, hands down.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
