On the comparison of the particle emitter to the PD laser - what that does not show is that the PE is considerably worse at PD vs anything fast - those screenshots do not show the chargeup and chargedown differences, and the turn rate only in words.
The PD laser turn rate is 100, it has no chargeup, and chargedown in 0.25
Particle Emitter turn rate is 30, it has 0.33 chargeup and chargedown is 1.0
Turn rate is vastly increased (double or tripled I think) if a weapon is not firing, and I believe chargeup and chargedown count for that as well.
Effect - Particle Emitters are much worse than PD lasers (and even Mining Lasers) at stopping lots of missles - sure you can kill it faster, if you can turn fast enough, but it will be at least a second before you can engage the next target. And they can be completely evaded by fast fighters on attack runs. I have watched this extensively 8-)
Relying on just Particle Emitters to stop a lot of missiles or fast fighters is a good way to get your ship killed--the effective dps drops massively when you take into account target switching time. Where they excel is as multipurpose weapons - good vs bombs, tough but slow missiles, slow fighters, and ships. I mix mine with Mining Lasers, or Coilguns from MVS, but PD lasers work as well. I also view Advanced Turret Gyros as essential for any ship that has Particle Emitters, and that still doesn't get them up to as fast as PD lasers.
They are good, but they are not a PD panacea, and should not be balanced as such.
Edit: Also, I am not seeing the post you were quoting as of that date, was it removed? Vanilla+ seems appropriate to me. If somone going to criticise a weapon with a comparison it should be a full comparison. The weapon card stats definitely do not tell the whole story.
