Well, then, it's really a mixed bag: With QR Avios you will likely see more award availability on Avios-based airlines, but you will also see carrier surcharges on most redemptions; with AAdvantage, more availability on AA, less availability on some other carriers, and no surcharges on any carrier except BA/IB.
