Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier infrastructure. The one platform every AI dev eventually uses.
