Delay and Verb here. I forget the names because the names are terribly unremarkable, but that Delay... man I'm surprised how little futzing I have to do with it. Switch the note length, kill or change the center channel, and maybe a lo-cut and BAM. 
 
Verb too. There's a sweet spot between Perfect Space and the Sonitus Verb...I used to use RVerb all the time...but this one is coming up fast. I tend to just want a quick-using verb where I can either get my vocal plate or instead a longer, darker verb and this one can do both pretty well.
 
Haven't dug into the rest too much yet. The spatializer (whatever it's called, the stereo widener one) I'm starting to get into for my Master bus fx-chain. 
 
The only complaint (aside from the names, but I forgive them that) I have is that they use that totally lame retro hardware UI look, with knobs. Knobs and knobs and knobs. With a mouse a knob is the worst possible UI metaphor, a touch-screen too. 
 
That aside so far all of the plugins in that suite are pretty great. There's a bit too much overlap but they're quite good.
 

Yeah they don't look the best.

I like their reverb better than breverb, so I guess that makes it my default choice.

I also really like the Chorus. And the Delay. Oil can is something to look into. It has.......that something!

I like the compressors. They have a sound unto themselves. I don't have experience with high quality hardware so I can judge these plugs vs the real thing. But I can say they have a good sound to them that I like.

Another one of their plugs that deserves a look is Echos.

All in all these are very good plugs. I have the whole bunch.

Brickwall, Stereo Widener and Blueverb are my favorites from the lot.

They won't work in X2 so I can't say.
