Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for designer-led sites. S-tier if animations matter.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
