which lasts longer.. coilovers or spring/shock

[TheSparo]

im curious about this, if both are used the same, which will last longer and which will be gone quicker... from what i've gathered, coilovers wear out quicker, is that true?

and another question, can you get pillow mounts for KYB AGX's ? and how much are they? (for a GC and AGX combo)

coilovers are rebuildable which is a nice feature...and if taken care of properly i don't see why they would wear a significantly greater amount or in a shorter period of time as opposed to a spring and shock combo...
