Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for speed. When latency is the product, start here.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
