For head-to-head approaches, I'd say Quads and Pods will be better, because you'll have a far longer engagement range to begin firing, and it suggests you'll be fairly lined up with your target. The short effective engagement range of BLC's means that in a head-to-head approach, your window to shoot will be extremely short before you've already passed each other, and in the meantime, you'd be getting pelted by an opponent's longer-ranged weaponry.
It all depends on your flying style. If you get into a turning war after the initial pass, BLC's will be better in that situation. But if you disengage after the initial pass to line up another head-to-head joust, Quads will likely serve you better.
