Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for model-shopping. I use this for every prototype before committing.
