Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.B-tier. Still early. Manus is more flexible for less money.
