| Kai's verdict | 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 inside Photoshop (Generative Fill). B-tier standalone. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
