We will start with the attic conversion next week and are facing a decision. Do I need counter battens under the drywall panels, or is a simple cross batten sufficient?
My concern is not the cost or effort, but the gain in usable space.
What are the advantages and disadvantages of both options?

If the lower edge of the rafters is even and perfectly aligned, a simple batten measuring 24/48mm (about 1 x 2 inches) (grade S10 or S13) or a substructure using drywall profiles from well-known manufacturers is sufficient. The spacing should also follow the manufacturer’s specifications depending on the board thickness, for example, 30cm (12 inches) for a 12.5mm (0.5 inch) single-person drywall board measuring 60 x 260cm (24 x 102 inches).
If the underside of the rafters shows greater variations in height, a counter-batten with adjustable screws should first be attached and aligned. This makes the subsequent work easier if a high surface quality is to be achieved, one that remains good even under grazing light. The adjustable screws are not cheap but very practical to use. In my experience, drywall profile systems are more cumbersome in this regard.

The spacing between supports should follow the manufacturer’s specifications, depending on the thickness of the panels—for example, 30cm (12 inches) for a 12.5mm (0.5 inches) single-person drywall panel measuring 60 x 260cm (24 x 102 inches).
If the rafter underside shows greater height differences, a counter-battening system with adjustable screws should first be screwed in and aligned. This makes subsequent work easier if you want to achieve the highest possible surface quality that holds up even under grazing light. The adjustable screws are not cheap but very practical to use. In my experience, drywall profile systems are bulkier and less convenient for this purpose.Very well explained!
