Best Image Upscaler today (images with people & faces)

Hi everyone, I was wondering what is today's (June 11 2026) SOTA Image Upscaling models or solutions?

My use case is specifically photos with people (faces, etc.). So preserving subject likeness is extremely important.

I've been using the Topaz suite of models, but I'm probably missing out on other models (open or closed source).

Curious to know what's your experience and what do you consider SOTA today?

Thanks all!
