Nano Banana Pro vs Seedream 5.0 Pro
Nano Banana Pro is the premium Google image model; Seedream 5.0 Pro is ByteDance's flagship at a fraction of the price. We ran both through the same twelve prompts to see what the difference buys.

Which to use
Nano Banana Pro on quality, Seedream 5.0 Pro on value, and the gap is smaller than the price gap. Seedream set the poster, drew the chart correctly, made a clean edit and left the banner's copy space empty; it lost on the logo, where it drew a chain link with no bicycle, and on the product shot, where it cut a hole through the dripper's base. Nano Banana Pro was near the top of every prompt. If you generate a lot, Seedream; if the image is the deliverable, Nano Banana Pro.
What others found

Seedream excels at the structural 'vibe' and factual layout but struggles with the granular 'logic' of the text itself.

Nano Banana Pro's text rendering and speed usually make it the faster choice for thumbnails, while Seedream 5.0 Pro is stronger when you need to precisely edit one region of an existing thumbnail without changing anything else.
