It doesn't necessarily suggest the image on the right is slightly better, but I felt from looking at it, it could stand up to more sharpening (through deconvolution).
When I looked at them side by side, I feel the image on the left is actually a bit sharper (it's had more processing of it, already), but it lacked colour depth, contrast and was too yellow. Maybe that's why people (myself included) favoured the right one initially.
Because the left image had already had deconvolution applied to it, I went light on it so as not to oversharpen it and introduce any artifacts. It may have stood up to 3 iterations, but I didn't try it. I did 2, it looked good, so I stopped there
Sometimes there's no method to my madness
