| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier. Category-defining UX. If you take notes in meetings, switch this week. | A-tier in its niche. The only one that actually gets emotion right. |
