Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for academic research. Nothing else comes close for systematic reviews.	S-tier for model-shopping. I use this for every prototype before committing.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
