Dall-E is worth the $20 premium subscription monthly in the quality of rendering and the finesse of details it provides. I also found it most-effective at altering the original image based on specifications ("make it rose gold").
Free for CU Boulder students, Canva Design offers a new AI-generated tool called "Magic Media" that nicely renders image from text. I'm not wild about the non-Arabic numbering included on the watch face, but Canva gets high marks for following the prompt in sleekness of design.
Formerly known as Adobe Spark, this free and easy-to-use version of Adobe now offers AI image generation. While the prompt could have been more closely-followed (I found this watch more athletic than sleek), the end result is passable. This is also the only AI that seemed to incorporate a pin-prick portal (presumably needed for blood glucose monitoring).
Stable Diffusion's image generator was underwhelming in my opinion. The quality of the image was questionable with telltale skin quality (looks computer generated).
Midjourney's imagery was moderate, but I've ranked the AI image generator last due to the logo watermark and the slightly less modern aesthetic in the product design.
