Based on your sample (and your sample only as I only have Waifu2x on my computer), I think Topez's is actually not bad.

I would prefer Topez's over waifu2x's "oily (overfiltered feeling)" result if not for the artifact introduced by JPEG - which Waifu2x definitely has a lead on removing them.

Yes, the Waifu2x one is more "clean" but also it also loses lots of details (see the texture on her shoulder etc.).

I wonder if the source file is png, it may have even clearly better results than Waifu2x.
I'm pretty sure those are not "details" on her shoulder, they're just noise/artifacts, but I will do another test with very clean images and pure upscaling.

Here's the result:

Topaz Labs and Photoshop somehow re-introduces jpeg artifacts into the image where none existed....

I also just tested straight up photograph, and there really isn't much of a difference. Gigapixel looks sharper but if you just sharpen the other two they basically look identical.

I insist that Gigapixel is just a scam, like many of their other filters.
