the value is: the absence of text where you expect it, and the presence of garbled text, are dead giveaways of AI generation. i'm not sure why you are being downvoted, compositing text seems like a legitimate alternative.
it seems like the value is that you don't need another tool to composite the text. especially for users who aren't aware of figma/photoshop nor how to use them (many many many people)
And if you want the text to faithfully follow the surface of the object (ex tattoos) I don't think the post AI gen manual editing approach is going to be so straightforward.
