| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. |
