The short version

Only Stable Diffusion has a free tier, so it costs nothing to try first.
Each has a real cost: Factory the $100 per month Plus tier only grants about 5 times the usage of the $20 Pro tier, so usage scales sub-linearly with price, as of August 2026.; Stable Diffusion generated images have lower resolution and quality at non-standard dimensions

Stable Diffusion

Generated images have lower resolution and quality at non-standard dimensions
Struggles with complex multi-object prompts and text generation
Poor rendering of human hands, limbs, and faces due to training data limitations
Trained primarily on English-language descriptions, reinforcing Western cultural bias
Requires significant GPU computational resources for local deployment
