I never used Sora but I recently tried Google Flow and the results are quite good. I have the feeling that Nano Banana 2 has been the image generation champion since it's release so maybe OpenAI feels that they cannot outcompete Google on this task?
On my experiments on GenAI Image Showdown, Nano Banana Pro slightly edges out NB2, though I'm not sure the cost difference makes it worth it.
And in pure qualitative terms, I'd agree that NB2/NB Pro are still on par with gpt-image-2, but gpt-image-2 is far easier to steer and is significantly better in terms of prompt adherence.
