I've had the Frazz for a while so I can talk about that.
First of all, the gate option I say is a triumph. I especially like the location of it so while I play rythm I leave it on, but if I start tremolo picking I can just move it over with my feet. On the higher gain settings, there is some hiss that bleeds-through the gate, but I prefer leaving the gain so it's right before a spot where there is bleedthrough, because then it's silent when you're not playing, but doesn't sizzle out on sustained notes and if you want, you can still coax some feedback if you stand really close to your amp. The mix control is a great effect to have on a distortion, I tried it on my friends acoustic, and it turned out lovely! (if you can use lovely to describe distortion) The volume control reminds me of my big muff's, after a certain point it doesn't really make you louder very much, it just makes it sound like your amp is exploding which I like, but hey, I'm a muff lover! To be truthful, the only thing I find annoying about the Frazz is the sizzle knob has to be changed each time you move another knob, and is rather sensitive. Other than that, I love it!
I've only had the Cosmichorus for a day and I didn't get to play very much (went to four concerts that day

) I must say that it is the best chorus pedal I've ever played! Beat out a vintage small clone... It can definetly go as fast as a small clone! I brought it to a friends, and we both love using it as a vibrato! Some settings get pretty flanger-esque too. Ryan, keep an eye out, ZVEX may be coming out with a ZVEX Chorus-Cosmi Factory.

better check the guts of that one!
