Nunu,
I have Fresco Rose and Rubenesque and I picked up Perky which is awesome, I compared all three and on my NW15 skin, Perky is a more pinkier-orange toned Rubenesque and is a Satin finish which is less shimmery than Rub.Frost finish but still good colour reflection.
I find these Fafi pps to be creamier than some of the other I've tried (Soft Ochre, Painterly etc) and I'm really loving Layin Low (Cream)--so smooth, and an awesome base for a neutral look (even on its own).
Do you use your McQueen paint pots a lot? If you do use Other Worldy a lot, I'd definitely try Rollickin, as it has great application and such a pretty reflective colour.
Honestly if I could afford it, I would buy them all (Girl Friendly seemed to me to be like a matte type of Fresco Rose but b/c I love Fresco SO MUCH I prob. would have got it too!)
With that being said, perhaps MAC is getting better with the paintpot formulations and I'd anticipate more colours later down the line (I mean its been less than a year since they were introduced and there have already been quite a few!)
I'm debating picking up Nice Vice--so pretty but I rarely wear purples anymore....but if its around when I order next I'm sure I'll get it! Oh and not sure I made it clear, I bought Perky and Layin Low and I have Fresco Rose and Rubenesque already (used to have Delft, Artifact and Greenstroke too but used it only a couple times, then sold them)
