Midjourney vs Leonardo AI for consistent character sheets

Short answer
- For highest visual/artistic fidelity with quick iteration: Midjourney. For the most reliable reproducibility across poses, color variants and batch workflows: Leonardo AI (or a fine-tuned Stable Diffusion/DreamBooth pipeline).

Recommendation
- If your primary need is consistent character identity across many poses and color variants (production character sheets), use Leonardo AI or a fine-tuned model (DreamBooth/LoRA) and leverage Leonardo’s project/batch tools. If you want highly stylized, one-off sheets and fast creative exploration, Midjourney is faster and often prettier out of the box.

Decision criteria (how to choose)
- Reproducibility: Leonardo > fine-tuned SD > Midjourney (Midjourney’s --seed works but is sensitive to model version and extra prompt/context).
- Prompt control & flags: Midjourney has clear flags (--seed, --stylize, --ar, --quality) and strong prompt-language behavior; Leonardo provides UI-driven controls (seed, style lock, batch) and better project persistence.
- Identity consistency across poses: use fine-tuning (DreamBooth/LoRA) or Leonardo’s subject training options; Midjourney alone struggles for pixel-perfect identity across many poses.
- Batch generation: Leonardo’s project/canvas and batch export are more production-friendly; Midjourney can batch via Discord/commands but needs manual bookkeeping.
- Cost & scale: Midjourney subscriptions are predictable; Leonardo credits and training can add costs. Fine-tuning a local SD model has upfront effort but lower per-image cost at scale.
- Skill level & team size: Midjourney is easiest for solo artists. Leonardo and fine-tuning require more setup (useful for teams and repeatable pipelines).

Practical checklist to produce reproducible multi-pose sheets
1. Collect reference set (front/side/3/4 faces) and color palette; label files.
2. Choose approach: prompt-only (fast) vs subject-train (recommended for consistency).
3. If training: create a small subject model (DreamBooth/LoRA) or use Leonardo’s subject training—test with 5–10 prompts.
4. Lock model version and record it. Save exact prompt text, seeds, and parameter flags.
5. Use a single reference image + seed per character, then vary pose tokens in the prompt ("character-name, full body, running pose").
6. Use style-lock / style preset to freeze look across runs.
7. Batch-generate variations (Leonardo projects or Midjourney bulk commands) and export with filenames that include seed, prompt, variant index.
8. Do inpainting/corrections rather than regen when you need a small fix—keeps identity intact.

Best-for / Avoid-if
- Best for Midjourney: rapid concept sheets, very stylized art, small batches, low setup friction. Avoid if you need near-identical identity across dozens of poses or production-level reproducibility.
- Best for Leonardo (or fine-tuned SD): consistent character across many poses, production pipelines, batch exports, color variants. Avoid if you want instant “artistic” results with zero setup or can’t invest in training/credits.

Extra tip
- Use ChatGPT (or your prompt manager) to templatize prompts and automatically inject seeds/pose tokens into batches—keeps results reproducible. Also store a single JSON or spreadsheet with: model version, prompt, seed, style, and reference links.

If you tell me your budget, target number of poses/variants, and whether you can train a subject, I’ll give a concrete prompt + batch workflow for the tool you prefer.
