Short answer / recommendation
- If you need repeatable, parameterized product shots for 50 SKUs with straightforward bulk export and project templates: choose Leonardo AI. It has built-in project templates, batch-generation flows, and an API-friendly workspace that makes automation and consistent outputs easier.
- If your priority is the absolute “art-directed” photographic look and you can invest developer time for Discord/API automation: use Midjourney.

Why (decision criteria)
- Consistency & parameterization: Leonardo wins for templates, tokenized prompt placeholders, and per-project settings. Midjourney can be consistent but requires more manual prompt discipline (or Discord bot scripting) and careful use of seeds/versions.
- Bulk / export: Leonardo provides more direct bulk generation/export tooling and a UI for job management. Midjourney relies on the Discord workflow and third-party wrappers for true bulk automation.
- Output style & quality: Midjourney typically gives a wider “premium/artistic” range out of the box. Leonardo gives excellent photoreal output too, and is easier to lock down for product-accurate renders.
- Automation hooks: Leonardo has a more developer-friendly product workflow (API/web UI batches). Midjourney can be automated via its bot/Discord and community-built APIs but is less turnkey.

Practical checklist to produce 50 SKU mockups
1) Define a single canonical product shot (angle, lighting, shadows, background color) and save a high-quality reference photo.
2) Build a prompt template with placeholders: e.g. “product: {SKU_NAME}; material: {MAT}; color: {COLOR}; camera: 50mm studio shot, softbox lighting, white seamless background; photoreal, --seed {SEED} --ar 4:5”.
3) Create a small 5–10 SKU pilot set to lock prompt wording, seed behavior, and negative prompts.
4) If you need brand consistency, train or pick a small custom model/LoRA (optional) or use provided preset styles.
5) Automate generation: use Leonardo’s batch/project UI or its API; for Midjourney, use a Discord bot script or third-party API to push prompt templates programmatically.
6) Post-process pipeline: background removal (or keep transparent), consistent color-grade LUT, standard resize/unsharp mask, and file naming convention.
7) QA pass: check scale, reflections, text legibility (if labels), and SKU metadata mapping.
8) Bulk export: download high-res assets and generate CSV manifest with filenames and SKU metadata.

Best-for / Avoid-if
- Leonardo: Best for teams needing quick, repeatable production, templates, and easier bulk export. Avoid if you require ultra-creative or heavily stylized art that only Midjourney’s models produce.
- Midjourney: Best for highly creative, premium-looking product photography when you have designer taste and developer time for automation. Avoid if you want a turn-key bulk-export + template workflow.

Budget, skill, and team notes
- Budget: Leonardo tends to be more cost-effective for high-volume, thanks to built-in batch tooling; Midjourney can get expensive if you rely on upscales/variations frequently.
- Skill & team: Small non-technical teams will iterate faster in Leonardo. Solo designers or art directors who enjoy prompt engineering may prefer Midjourney.

Final recommendation
If you need a production-ready pipeline for 50 SKUs with minimal engineering lift: use Leonardo AI. If your priority is the most distinctive, high-end look and you can script the Discord/API workflow: pick Midjourney.

(If you want, I can draft the prompt template and a small automation script you can run for your 50-SKU CSV.)
