Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-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.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
