I think T maybe needs to clean a brush once in a while and maybe her issues with "poor pigmentation," and "wierd overcoats/hard surface" that make it hard to get a swatch from powder products would not be so bad. JMHO, don;'t throw rocks.
I never got the EE quad, had too many similar colors so maybe it was crappy but the colors in the PP quad were all fine for me. I think I use PP in the V of the eye, so did not really have to blend it much but it definitely has color pay off and no problems with patchiness or such. It is probably dupeable but the reason I probably love it and will be getting the single is I never depot my quads so I want the singleton because it is really hard for me to find plum, pruple or wine colored e/s that don't make my eyes look like pink eyed rabbit effect or irritate my eyes. (I think there is something in the red or purple pigments that is irritating for me, and PP doesn't do that.) So, that is why it is one of the few e/s I will actually back up.
