So... I'm not quite sure why I would use this over using GPT/Claude/Gemini directly for design?

Bitter lesson, etc, and training an entire VLM to prevent text overlap seems a bit much, especially since GPT 6.* /Claude 5.*'s vision are good enough that it rarely ever happens for me, and if they do make a mistake, it's generally a 5 minute fix?

I work as a product designer, and your right, mostly people aren't using Figma's AI products (at least in my circles). 80% of my time is spend in Claude Code/Design. 20% in Figma doing manual work when I really need to explore things and spec out in detail.

Figma's current AI Agent is essentially useless, especially when compared to these other tools. Not sure what effect the work in this post will have, but even if it's great I feel that designers have already left Figma and are working elsewhere.
