Best for packaging mockups: Midjourney or Leonardo?

Short answer
If you need pixel‑crisp dielines and guaranteed legible type for Amazon listings, don’t rely on a pure image-generator alone. Best practical path: use Leonardo AI to create high‑resolution label/texture artwork (or concept renders) and then apply that texture to a proper 3D mockup or real photograph for final reflections and lighting. Midjourney gives beautiful scenes fast, but historically struggles more with small readable text and consistent specular reflections.

Why this recommendation
- Text legibility: Both generators struggle with tiny, precise type when you treat text as “generated pixels.” Leonardo gives stronger control for iterations, inpainting, and producing clean high‑res texture plates you can edit. Midjourney can produce convincing scenes but often needs manual cleanup of typography.
- Realistic reflections: True physically accurate reflections are best produced by a 3D renderer (Blender, KeyShot, or commercial mockup services). AI can fake reflections well at a glance but will be inconsistent across angles and thumbnails.

Decision criteria (pick what matters most)
- Pure speed / concept comps: Midjourney (fast, pleasing overall look). Avoid if you require crisp, legally accurate copy.
- Control & iterative tweaks to label textures: Leonardo (better canvas/inpainting controls and export workflow).
- Need photoreal, consistent lighting and specular highlights: 3D render pipeline (Blender/KeyShot) + use the AI output as the texture or reference.
- Budget/skill: If you don’t have 3D skills, use Leonardo + mockup service or hire a compositor. If budget is very low, Midjourney + Photoshop touchups is the cheapest.

Best‑for / Avoid‑if
- Best for Leonardo: creating high‑resolution dieline-aware textures, quick inpainting to replace label art, iterative texture adjustments.
- Avoid Leonardo if: you only want a single artistic scene and don’t want to composite or render further (Midjourney can be faster for that).
- Best for Midjourney: rapid scene mockups and styled lifestyle shots.
- Avoid Midjourney if: text legibility and exact dieline placement are mandatory.

Practical checklist (step‑by‑step)
1. Finalize vector dieline and typography in Illustrator (keep text as editable vectors). Export a 2–4× label texture at 300–600 DPI (PNG/TIFF, sRGB).
2. Use Leonardo to generate texture variations and do inpainting on that exported texture if you want stylistic elements; keep the exported file lossless so you can swap it into the 3D model. (CTA: Leonardo AI)
3. Apply the texture in a 3D mockup (Blender/KeyShot) with an HDRI for reflections; set material roughness/specular for realistic highlights.
4. Render at Amazon image sizes and check downsampled legibility (thumbnail test).
5. Composite final scene in Photoshop if needed (add subtle film grain, adjust highlights). Export sRGB, correct color profile and required pixel dimensions for Amazon.

Final note
If your workflow or team is small and you can’t do 3D, generate the label in Leonardo, place it on a high‑quality photographed mockup, and manually replace text with vector layers for guaranteed legibility. For enterprise-level listings where legal copy must be perfect, always keep type as vectors and only use AI for creative artwork, not the final readable copy.
