| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for designer-led sites. S-tier if animations matter. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for realtime. If latency matters more than voice catalog, start here. |
