Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier infrastructure. The one platform every AI dev eventually uses.A-tier. Best for teaching a kid to code in 2026.S-tier in the agent category. The first one I'd give to a non-technical friend.
