I do find the Sonnox overpriced, and am not keen on iLoc. Plus too much room given to knobs vs the curve screen for my taste. Also, I don't think it has a Mid/Side option.
The Oxford Eq was born as a digital equalizer in the Sony OXF R3 digital console. Picture below shows the equalizer on the right and Compressor on the left. I believe the plugin interface was not just a copy of the hardware original but was chosen for the daw world because engineers like knobs more than screens....of course this may have changed. The Sonnox Eq apparent short coming you mention have nothing to do with the sonic excellences this equalizer delivers and it is one I use everyday. YMMV
