Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for model-shopping. I use this for every prototype before committing.
