I run a fairly comprehensive model comparison site (generative and editing). In my experience:

NanoBanana and Flux Kontext are the models that get closest to traditional SDXL inpainting techniques.

Seedream is a strong contender by virtue of its ability to natively handle higher resolutions (up to around 4 megapixels) so you lose less detail - however it also tends to alter the color palette more often then not.

Finally GPT-image-1 (yellowish filter notwithstanding) exhibits very strong prompt adherence but will almost always change a number of the details.
