I like the compilation tapes that Unrest does too, they're generally just filled with quality stuff even if there's here and there something I like less.
Hated Perversions is great indeed, due to both the tracks and the layout. Gender with no purpose, other than... and Animal Bizarre are nice too, due to the tracks and the samples in between.
When it comes to CMI, I only have Flowers Made of Snow, it's been years since I listened to it, but I really liked it as well.
Let's not forget All My Sins Remembered, I'm not fully through it, but so far I've been impressed by the general quality of the music, the layout and the writings.
Transmissions of Hatred is something I really should get, judging by the line up.
Projekt Neue Ordnung that Tesco is going to release seems like it should be great too, not certain whether I'll get it though, will depend on my finances...
In general I've got the feeling that Noise/Industrial/PE compilations are more interesting than Black/Death/... Metal compilations. One reason might be that Metal compilations most often seem to have some sort of promotional aim. This does of course also count for the Unrest compilations for example, but there also seems more quality control...
