Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier infrastructure. The one platform every AI dev eventually uses.
