Key difference
Midjourney (Tier 2) uses keyword prompts with :: weighting and --no inline negatives. Leonardo AI (Tier 1) uses CLIP-tokenised (term:1.3) weighting with a separate negative prompt field. Both accept 1,000-character prompts but use different weight syntax and negative prompt mechanisms.
Choose Midjourney when you want atmospheric stylisation through Discord. Choose Leonardo when you need CLIP weighting, a separate negative prompt field, and a web-based UI.
Why this matters for your workflow
Choose Midjourney for atmospheric, stylised compositions with Discord-based workflow. Choose Leonardo for fine-grained CLIP weighting, a dedicated negative prompt field, and a web-based UI with multiple model options. Promagen writes the correct syntax for either platform.
