Nano Banana vs Seedream 5.0 Pro
This pair is less of a head-to-head than the others, because the two models are good at different halves of the work. Nano Banana is where an image gets made. Seedream 5.0 Pro is the model behind Edit Image: mark a region of a finished picture, say what changes there, and the rest of the frame is preserved.
That split shows up in the specifications — most obviously in resolution, where Seedream 5.0 Pro stops before 4K.

Which one to pick
Seedream 5.0 Pro
This is the job it exists for on Labnana. Mark the region, write the change, and keep every version side by side. Regenerating the whole frame with another model gives you a different picture, not a corrected one.
Nano Banana
Seedream 5.0 Pro supports 1K and 2K only — the resolution row says so, and the generator will not offer 4K when it is selected. Nano Banana runs to 4K on a paid plan.
Nano Banana
The standing free allowance sits on Nano Banana Pro: generations on sign-up, more from each daily check-in and from referrals. Seedream 5.0 Pro has no model-specific quota and bills against universal credits, so exploratory rounds run out faster there.
