Our Take on Each
Adobe Firefly
Best for: Commercial-safe images in Adobe apps
Firefly's edge isn't raw creativity, it's being commercially safe and baked into Photoshop. For designers already on Creative Cloud, Generative Fill alone justifies it. As a standalone generator it's less exciting than the pure art tools, but that's not really who it's for.
Stable Diffusion
Best for: Free, private, customizable generation
Stable Diffusion is for people who want total control and zero per-image cost, as long as they've got the hardware and the patience to set it up. It's not plug-and-play, and results swing with the model you choose, but nothing else offers this much freedom for free.
Verdict: Adobe Firefly or Stable Diffusion?
Budget is the quickest tiebreaker: Adobe Firefly starts at Free / $9.99/month, Stable Diffusion at Free (open-source). Beyond price, Adobe Firefly scores marginally higher with users — though the "right" choice really depends on how you'll use it.
