Kai's verdictB-tier. Useful for first drafts. v0 is the better bet for shipping code.S-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.
