Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
