Kai's verdictS-tier for realtime. If latency matters more than voice catalog, start here.A-tier for designer-led sites. S-tier if animations matter.B-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.
