Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for academic research. Nothing else comes close for systematic reviews.
