well, according to specs the UAD thing actually is a Neve coop - I have no idea how trustworthy it is, but it seems well-regarded at least.
Some information about various EQs can be found
here, the topic
Example EQ Phase Plots gives an introduction about what makes an eq's character.
You may then switch to the respective model, but afterall a bunch of phase and intensity curves don't really give an acoustic impression.
Bottomline is that basically all digital vintage reincarnations follow a very simple paradigm:
measure a physical unit and weigh controls in your own general purpose device accordingly.
The Nebula-3 convolution (snapshot) approach is probably the most straight forward in this context.
I remember their EQ (wasn't even a 'classic' model) to be stunningly intense.
For sure a color you would want in your arsenal for
occasional use, but not my cup of tea for general purpose at all.
Alfonso's (Adern) Mojo virtual guitar amp gives a very good impression that slaving a vintage model is a technical dead-end.
It's not a marketing one, tho... as people
will buy the GUI rubbish for the sake of the imaginary saved cash or feeling in some exclusive league anyway...
After all a guitar amp is nothing but a moderately complex EQ - if you don't drive it too hard.

Mojo isn't modelled after any specific amp, but has been carefully 'tuned' by a knowledgeable guitarist.
As a result it can compete with top of the line gear, given you feed it a proper signal.
Imho similiar things apply to Scope EQ.
You may need a 2nd stage (or phase/drive context) to setup more 'spectacular' results, but that could as well be a musical advantage.
Too many production suffer from the too-much-of-everything syndrome.
For me ISON is all I need, but then... I don't even use that one much, as I'd rather change the source than insert...
One can buy a phantastic bass with tremendous sustain, detailed articulation and whatever, but in the end it's (usually) a simple Fender Jazz or Precision that makes it on the track...
