| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for text-in-image. Use this for posters, Midjourney for art. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. |
