Tactical lasers are great for long-range PD, provided you do not have a lock on a target. A lock seems to confuse the lasers for some reason. Tactical lasers are mediocre for tracking fast turning Salamanders once they get close. Because of long range and passthrough, tactical lasers can fry several missiles long distance away before they become a threat. You do not use Tactical Laser as short-range, immediate response PD. The idea is use tactical laser as multi-purpose weapon and rely on shield to absorb missiles that get past your lasers.
PD Laser is faster and more flux efficient than Tactical Laser, making it better for close-range defense. Not as good anti-missile as burst PD, but useful if you will be swarmed for more than a few seconds.
LR PD Laser is mediocre, but useful enough if you do not have better (e.g., Easy bounty hunter start).
Burst PD lasers are great for stopping a few missiles, but they quickly become nearly as mediocre as LR PD Lasers once they spend all charges. Burst PD is what you use when you need stopping power in an instant, not for continuous defense.
I find Burst PD works better, but I play with a ton of mods with a lot of faster moving missiles. PD or LRPD is... okay for clearing a couple stray annihilators or a salamander. But I find that even with several of the things focusing on single missiles, it takes them too long. A couple PD or LRPD overlapping can't even handle a volley of annihilators let alone the endless rocketry of the medium slot annihilator.
None of the standard light energy PD can handle missile swarms (and probably by design). Burst PD does not have enough charges to blast more than a few missiles or fighters, and the rest lack stopping power.
I often prefer Tactical laser or PD Laser because they are cheaper and more common than burst PD (which is somewhat rare) and do more DPS over time, making them useful for general-purpose.
I'll just drop this thought in here: energy PD was hurt a lot by the removal of bonus damage from flux.
As compensation, they got lower OP cost and (except for Burst PD) more range. Mining Laser got a large enough range increase that it is no longer worse than useless, PD Laser is usable without Advanced Optics, and Tactical Laser is very good overall. That said, LR PD Laser is really mediocre, almost an overpriced version of the Mining Laser; and Burst PD was not improved enough for its cost. Burst PD needs at least three charges for its high cost, and possibly reduce cost by one more OP.
