| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Close second to Cursor. If $5/mo matters, start here. | S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it. | S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work. |
