jjss49 is correct in assessment of the two brands and obviously a bit of a cheerleader for the active ATCs. So am I, but then it's not my system to listen to. I've the ATC SCM 40A and have unabashedly touted their talents of immediacy, dynamics and accuracy.
If you go with the ATC passive, jjss49 is completely correct that upstream is particularly salient. You need lots and lots of clean strong stable current to hold them together.
