Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
