Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
