Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for social/casual. B-tier for serious work. Good entry point.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.
