sure there are degrees to uniqueness.
I assume woops was talking semantics / language use. Still, "very unique" is like "so true" and "very best" - none of these expressions make sense in terms of some kind of formal definition, but we all get it... a more pedantic way to say "very unique" would be "very distinctively unique".
Mention of Dean Roberts' 'All Cracked Medias' made me think of Polwechsel and the associated Viennese bods. Roberts, although a Kiwi, has been working with one of the Polwechsel bods and Brandlmayr from Radian / Kapital Band 1 / Trapist / etc. etc. under the name Autistic Daughters. They're more in a sort of quiet improv (with electronics) than anything like glitch, though. I'd be happy to list some suggestions.
Oh, did you ever hear any of the Sigma Editions stuff? Minit in particular? They had an album on Staubgold too, but the Sigma release was better. They did some great stuff. I thought of it because the label is run by two guys Dean Roberts was in a bad with back in the 90s. Parmentier, Rosy Parlane, it's all sorts of low-fi, sounds like it's on a 4-track home tapedeck, but also very of its time - turn of the century glitchiness that tend towards more emotional stuff.
