Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for speed. When latency is the product, start here.B-tier. Still early. Manus is more flexible for less money.S-tier in the agent category. The first one I'd give to a non-technical friend.
