Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
