From an insulation point of view, is there much advantage in using drywall rather than installing paneling sheets directly to studs?
Not from the point of view of insulation. But sheetrock with proper taping can help seal a wall against air movement. Of course the real air tightness should be accomplished with the exterior weather resistant barrier.
I've been in homes that only had T1-11 siding or similar, no OSB or plywood under-sheeting and they always felt cooler and drafty to me. If one was to install drywall and tape and mud it like normal then install paneling or T&G over that it should cut down on drafts, as Don suggests, and it might just add some intrinsic R value to the structure.

If I can piggyback a question onto the above, are there any moisture/condensation issues with adding paneling or tongue and groove boards onto ceiling sheetrock?
