Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
