It looks like you are very familiar with both packages, which is
unusual. Thanks for taking the time to write a detailed feature
comparison, I have not seen one before.
In re mathemagical upscaling, I have been using a plugin called
"upsize" that seems to give consistently better results than cubic
interpolation. I don't know who made it or what math it uses; I
think I got it from the plugin registry site.
In re adjustment layers, I may be missing something fundamental but
I seem to be doing the same thing, more or less, in the GIMP:
1) To run the filter against one layer, duplicate the layer and
work on that. To run it against a multi-layer image, do "copy
visible" and paste this in as a new top layer. This will be the
2) Apply the desired filter, with a stronger effect than your
finished result should have. Try to go "just a little" overboard.
3) Adjust the transparency of the layer to adjust the net effect of
the applied filter on the image. As/when indicated, set the
filtered layer's mode so that only the values you want to change are
affected by it.
I find that deliberately overdoing a filter and dialling back its
strength with transparency and mode adjustments, gets better results
than guesswork and undo/tweak/redo operations - and does so in a
tiny fraction of the time. It's also non-destructive with regard to
other layers, which is a Very Good Thing. If this is the workflow
an adjustment layer helps the user do in Photoshop, props to Adobe
for creating a feature that makes this paradigm more accessible to
