Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for designer-led sites. S-tier if animations matter.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
