Evaluate Midjourney when you want an image-centered workspace for developing a visual direction. Evaluate a specific Nano Banana model when its reference and conversational-editing workflow fits the task. Both now support image revision, so an old distinction between “art generation” and “editing” is too simple to guide a current purchase.
Researched and written by GPT, an AI. Recommendations are based on cited documentation; no hands-on performance testing is claimed.
Separate style from subject identity
Imagine a campaign using the same product in several illustrated scenes. The style should remain coherent, but the product must also remain recognizable. Those are two different requirements. A reference that influences color and texture is not necessarily a reliable instruction to preserve the exact object.
Midjourney documents Style Reference for visual treatment and an Edit Model for instruction-based changes and reference images. Its current version documentation identifies V8.2. Midjourney Style Reference, Midjourney Edit Model, Midjourney versions.
Google's Nano Banana guide covers a family of image-generation and editing models. Record the exact variant rather than treating every result bearing the nickname as the same system. Google image guide.
Use a brief with competing constraints
For the campaign example, supply a product reference, a style reference and a required line of text. Request three scenes that use the same product without copying the same composition. Then revise one scene while holding the other requirements fixed.
The proposed evaluation should score product fidelity, text accuracy and visual coherence separately. A strong style match does not excuse an altered label. A faithful object does not automatically produce an effective advertisement. We have not run this test or established that either candidate wins it.
Nano Banana Pro versus Midjourney
If your query specifically means Nano Banana Pro, Google's current model code is gemini-3-pro-image (Gemini 3 Pro Image). Keep that variant in the comparison instead of silently substituting Nano Banana 2.1 or another family member. The model name also does not identify a consumer subscription: an API, Google's app and a third-party editor can have different controls and allowances. Gemini 3 Pro Image.
A useful Pro-specific brief is a product card containing a supplied package, exact heading and fixed background treatment. Create the card, then request one local change. Inspect the label after every edit and record manual repair. Repeat with several products of different shapes; one attractive result cannot establish reliable catalog production. Google positions Pro for demanding visual work, but we have not measured an advantage over Midjourney.
Compare the operating model
Midjourney's subscriptions use GPU-time and queue-related allowances, with private Stealth generation restricted to certain tiers. Midjourney plans. A Nano Banana model may be accessed through an API or an application whose own plan rules apply. Gemini API pricing.
Those are not directly comparable units. Estimate how many accepted assets you need and how many attempts and edits each requires. If unreleased client material is involved, verify visibility and retention before uploading it. Do not assume that a paid plan is private by default across every product.
Keep version changes visible
An existing Midjourney workflow may use older reference features, while newer versions use a different editing path. A Google workflow may change when a different Nano Banana variant is selected. Preserve versions and source assets with the project so the team can understand why a later regeneration differs.
Prefer Midjourney if its creative controls and workspace suit the team and the required privacy tier fits the budget. Prefer the chosen Nano Banana route if its reference-editing behavior and integration fit the production process. The recommendation changes with the actual task, not with a universal label such as “more artistic” or “more accurate.”
Before committing, deliver one complete campaign set and have a reviewer inspect the files at final size. A gallery of isolated attractive images is weaker evidence than a consistent, usable set that survives a requested revision.
