Tactical Lasers work really well if combined with the Integrated Point Defense AI hull mod too since it makes all small turret weapons to prioritize targeting missiles over enemy ships, but allows them to target ships and fighters when there are no missiles in range. The mod also gives all your PD weapons, including all small turrets that the mod is turning into PD weapons, the best possible target tracking against all targets so it can improve their ability to hit fighters and frigates too when there are no missiles in range. And the mod increases all damage to missiles by 50% even for non PD weapons, so missiles that happen to get in the way of non PD weapons are more likely to be destroyed. And it stacks with the 50% increased damage to missiles from the Point Defense skill it can turn ships with lots of small turrets into amazing anti-missile/fighter platforms.
Flak cannons and Dual Flak cannons are really great for anti missile defenses too since they're aoe weapons and can hit multiple missiles per shot but require medium ballistic mounts and are kinda flux intensive at 50 flux per shot.
Burst PD Lasers and Heavy Burst Laser are both great against intermittent missile fire, but are less effective against a constant barrage. Both burst pd weapons benefit from the Extended Magazines hull mod because it allows them to hold more charges, but it doesn't increase the charge rate so it doesn't increase their effectiveness against a constant barrage situation. Burst PD are amazing for Phase Ships since the charges regen while they're phased which allows them to deal with missiles when they unphase and then phase when they're out of charges.
