Strapping Drywall to Ceiling rafters or just attach drywall?

We just finished converting an attic space over garage to a bedroom and it has knee walls and a cathedral ceiling. What is the difference between strapping the drywall to the rafters with 3/4 inch wood strapping and just screwing in the drywall to the 2x10 rafters? Is one method more preferred and is one way more beneficial?

Strapping is usually used to fix defects in the framing - joists with too much span or uneven. If the joists/rafters are uneven, shimming the strapping will help to level it out. It can also be neccesary to allow for more insulation and/or air space for ventilation.

Attaching directly to the joists/rafters is the most common method.
