What our research says

Adobe Firefly

Pick Firefly when the indemnity and the Creative Cloud integration matter more than raw image quality, because on quality alone it trails Midjourney and the frontier models.

Pros

Trained on licensed and public-domain material with enterprise indemnity attached
Generative Fill inside Photoshop beats round-tripping through another tool
Produces editable vectors rather than only raster images
Standard image and vector generation is uncapped on paid plans

Cons

Image quality lags the top standalone generators
Generative credits drain fast on video and premium partner models
Pricing is split confusingly between standalone plans and Creative Cloud bundles
Free tier watermarks output and allows very few credits

SeiSei AI

SeiSei AI's guest mode, three free images a day with no account, is a genuinely low-friction way to test quality before committing, and letting you pick the underlying model per job gives some control over cost versus quality. Beyond the free daily allowance, the mix of subscriptions and separate one-time credit packs makes the pricing a bit more to parse than a single flat plan.

Pros

Three free images a day with no account required
Choice of underlying model with price shown before generating
Both subscription and one-time credit-pack options exist
Annual billing cuts the price by roughly 40%

Cons

No company or location information disclosed
Per-model pricing means cost is not fully predictable until you pick a model
Entry subscription is $19/month, higher than some single-purpose image generators
