Now that I know exactly what you are asking for, i can better answer:
My experience has been this: Massive fates suck on PS3. Any instanced content is exponentially better. I have not read up on or done coil before so I am not sure how that stacks up with the rest of the instances (from a processing perspective). Playability I have not experience any difference, but I cannot fully make that claim until I do coil, which I think is what you are telling me.
