Det_Bullock: There isn't a "best" strategy, they are both correct, only the torp strategy is usually for the first wave of bomber to shoot it down as fast as possible before they get in range then you can get closer to the ISD or Frigate that releases them and you can use the second tactic.
I'd disagree. The strategy of shooting a TIE Bomber with 4x lasers (or a TIE Interceptor 2x) to cause HULL DMG and force it to return to its capital ship works best when they are at some distance from the capital ship. Why? Because it gives you a good delay before respawning a new wave, as a damaged fighter has to travel the entire distance to the capital ship and enter its hangar first.
Also, I don't like wasting missiles or torpedoes on TIE bombers. They take long to aim, and cost mission points.
