Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier for designer-led sites. S-tier if animations matter.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
