Choosing an AI image model from one impressive sample is unreliable. A better comparison treats each run like a small experiment: keep the creative brief stable, change one variable at a time, and score the outputs against the job you actually need to finish.

1. Lock the brief
Use one prompt with a clear subject, composition, lighting, aspect ratio and required text. Save the exact wording so every model receives the same task.

2. Freeze the references
If the job depends on a person, product or style, use the same reference set in every run. Changing references and models at the same time makes the result impossible to interpret.

3. Test one capability per round
Start with the base model, then test personalization, style reference or editing controls separately. For a Midjourney V8.2 migration, useful rounds are V8.1 baseline, V8.2 baseline, V8.2 with personalization, and V8.2 with SREF. Omni Reference remains a V7 workflow, so do not mix it into a V8.2 comparison.

4. Score the work, not the spectacle
Rate prompt adherence, composition, readable text, reference consistency and editability. A visually dramatic image can still be the wrong result if the headline is unreadable or the product changes shape.

5. Log the operational cost
Record generation time, failed attempts, credit cost and how many edits were needed before the asset was usable. This often matters more than a small difference in first-pass aesthetics.

6. Keep a decision record
Save the prompt, references, settings and a short reason for the winning model. The next campaign then starts from evidence instead of memory.
