Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.A-tier in its niche. The only one that actually gets emotion right.
