Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for speed. When latency is the product, start here.A-tier. Close second to Cursor. If $5/mo matters, start here.
