The oiling is a good point, but here is mine:
If you use fiber based papers, and you're ysing single weight papers, then - in my experience - the fibers in the paper will show much more clearly, than if you use a thicker paper.
This also goes for RC papers - the "normal" thickness lets the fiber traces cover it self, so to speak, and then the "only" advantage would be a shorter exposing time...
Also - IMO - fiber based papers can be rather difficult to keep as flat as neccesary for a good contact print.. RC is much easier.
I am kind of lazy.. so I go for the quick and easy..
