Short answer
Use Leonardo AI as your primary generator for 30 brand‑consistent social ad images/month. It gives more built‑for-production features (batch generation, workspace/templates, easier variation/export) and smoother private workflows for commercial use. Use Midjourney only when you specifically need its distinct, high‑artistic look for hero assets, and/or you have time to do more manual prompt work on Discord.
Why I recommend Leonardo for this brief
- Batch control & iterations: Leonardo’s Studio UI lets you run larger batches, create templated prompts, and spawn many variations quickly from a reference. That cuts iteration time for ads where you’re changing copy and minor layout, not the whole art direction.
- Consistency tools: Ability to lock references, reuse style templates and presets, and do image‑to‑image/inpainting at scale helps keep a tight look across 30 images.
- Team/workspace & export: Leonardo is generally easier for teams to share projects, export asset sets, and keep private workspaces (less friction than Discord).
- Licensing: Both major vendors offer commercial use on paid tiers—but check the current TOS for the plan you buy. Leonardo tends to offer clearer “private workspace/commercial use” options for production workflows; Midjourney also allows commercial use on paid plans but is Discord‑centric and historically has broader public training policies unless you pay for privacy. Do due diligence and get the plan that explicitly grants commercial rights and private usage if required.
When to pick Midjourney instead
Best for: hero creative, highly stylized or artistic brand moments where aesthetic uniqueness is the priority. Avoid if: you need repeatable, templated output or fast bulk production — Discord workflow and manual re‑rolling are slower.
Decision criteria (quick)
- Need for consistent batches and templates: Leonardo wins.
- Need for unique, highly artistic renders: Midjourney may win.
- Team size & collaboration: Leonardo wins (web UI, project sharing).
- Privacy/commercial clarity: Check plan TOS for both — choose paid plan with private/commercial options.
- Budget/skill level: Midjourney needs stronger prompt craft and manual steps; Leonardo is friendlier for less fiddly bulk work.
Practical checklist to set up production (30 images/month)
1. Legal & account: Purchase paid plan with commercial rights + private workspace on your chosen platform; document TOS snapshot.
2. Create a one‑page visual style guide: color palette, type/typography rules, logo placement, safe margins, and 2–3 approved reference images.
3. Build a master prompt template (use ChatGPT to draft variations): fixed style tokens, negative prompts, brand keywords, and variable fields for copy/cta.
4. Save reference images and lock a seed/preset where available.
5. Batch generate 3–5 variants per concept; use inpainting or image‑to‑image to adjust copy or hairline design differences.
6. Rapid QA pass: check brand compliance, export at required sizes, and label files with campaign/date/variant.
7. Archive prompt + settings next to final assets for reproducibility.
Hybrid workflow recommendation
Make Leonardo your monthly workhorse and reserve Midjourney for 1–2 hero images per campaign when you want a special aesthetic. Use ChatGPT to automate prompt templates and produce consistent copy/variable fields.
Notes
The “right” choice depends on budget, how much time you’ll spend fine‑tuning prompts, and whether you need API access or integrations. Confirm current licensing terms for whichever plan you buy before running commercial ad campaigns.
