| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier in its niche. The only one that actually gets emotion right. | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | A-tier. Best for cinematic image-to-video. Pair with Runway for coverage. |
