The verdict
Which one should you pick?
Flux
Pick it for
- Key art and concept frames where legible text in the image matters
- Environment plates and set-design variations at 2K or 4K, priced per megapixel
- Studios that want open weights and custom LoRAs running locally in ComfyUI
Stands out
- Open weights: FLUX.2 [dev] and the klein models can be downloaded, self-hosted and fine-tuned, with LoRA rights on the licensed tiers. Midjourney is closed.
- Pay per image with no subscription: FLUX.2 [klein] 4B from $0.014 per image, FLUX.2 [pro] from $0.03. Midjourney and Adobe Firefly sell monthly plans.
Watch out
- Video is new. FLUX 3 Video availability and FLUX 3 Image early access have been described differently across sources, and video pricing is not published
- Open-weights models are non-commercial by default, and commercial use needs a licence quoted by sales
Leonardo.ai
Pick it for
- Concept art and key-art stills that later become motion tests
- Animatic and previz stills turned into 5-second motion clips
- Custom-trained visual styles for a short film or music video look
Stands out
- Canvas-first editing (AI Canvas for inpainting and outpainting, plus a realtime mode) in the same tool as image and video generation
- Several model families under one account, including Leonardo's own Lucid and Motion 2.0 alongside third-party video models such as Kling 3.0 and Veo 3.1
Watch out
- Video is short (about 5 seconds on Motion 2.0) and not built for sequences or dialogue scenes
- Hosted third-party models are removed on short notice, so a workflow that depends on one can break mid-project
LetzAI
Pick it for
- Storyboards and animatics for pitch decks, shot by shot
- Testing one shot across several video models on the same board before committing credits
- Agency client review with preview links and comments
Stands out
- One workspace for storyboard, generation, shot-by-shot video animation and client previews, with no export step between tools
- Multi-model access in one subscription: 40 active base models on the models page, including Seedance 2.5, Kling V3, Veo 3.1, Flux and Nano Banana
Watch out
- Canvas and the assistant need a paid plan, and assistant chat draws from the credit balance
- Credits are non-refundable and generation prices can change without notice
Midjourney
Pick it for
- Concept art, key art and look development for features and series
- Storyboard frames and mood boards where the look matters more than shot control
- Client-confidential previs on Pro or Mega using Stealth mode
Stands out
- Stealth mode on Pro and Mega keeps confidential client and NDA work out of the public gallery, which the tools above do not offer on an equal basis.
- Consistent, art-directed default look across prompts with the V8.2 personalization profile, which is trained on your ratings rather than a LoRA you build.
Watch out
- No free trial
- Video is still the 2025 V1 image-to-video model, with no text-to-video or audio
