Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for data teams. S-tier if you already live in SQL + Python.
