@bigdoggproblemsaid I usually like the Rooks, if their King is safe and they don't have too many weak pawns.
I agree, I would add however that in order to make 2 rooks superior, the king needs to be safe from annoying checks by the enemy queen which too often lead to draws.
In general: 1. Two rooks can mate without further assistance, a lone queen cannot. 2. Two rooks can double attack something, the queen can only single defend. 3. The side with the queen must try for perpetual check, if there are no mating chances; this depends heavily on the pawn formation.
The following game is illustrative: the Black king (with two rooks) is chased around the board and finally finds shelter from White queen checks in an improbable location. The two rooks eventually mate.
