Default Modulation for PCM receivers (Z or S)??

Can someone provide some information pertaining to PCM receivers in relation to the following for jets. I am interested in how they differ in their ability to block interference from outside sources first of all. Secondly, I would like to understand how the "S" modulation receivers differ from the "Z" modulation in relation to safety when used with turbine engines, such as placement in relation to fuel pumps which may create range problems created from using a"Z" modulation receiver, or fail safe shutdown safety in flight with the "Z" modulation receivers.
I have a J.R. PCM10 "Z" modulation receiver I would like to use but only if it is as good as the "S" modulation or at least very close. Thanks in advance for any help...Gary
