| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
