In my opinion, your pic looks more filtered on the edges, like, more antialiased or something. In my script I've tried to balance between preserving detail and removing jaggies, and I don't think it's oversharpened, but that the slight ringing around edges is just more visible because of it being upscaled.
Due to how low the vertical resolution of the GOUT is, I don't think it can look much better. I'm still trying to improve the script though, but I won't go as far as to make it look like your pic. No offense of course!
No offense taken. Don't think I menat that you caused the ringing, it's in the original GOUT due to the fact that the original GOUT is oversharpened. It's just that your (good) sharpening has amplified the original (bad) sharpening.
