For ecommerce product mockups I’d pick Leonardo AI for faster iterations and repeatable branded variants—it has templates, inpainting, and batch/variation controls that keep composition and lighting consistent. Use a reference image, fixed seeds, and prompt templates for all variants. Midjourney can produce richer photoreal detail but is harder to guarantee exact consistency across many SKUs and model updates may shift results. Upscale with the built‑in upscalers then touch up in an editor if needed.
