Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier. Market leader with reason. Start here for serious video.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
