At some point with all these tier lists that crop up, I should give a tier list of tier lists. In which case this one rates a solid A. There are a couple of things that I'd quibble with but they're mostly a matter of extent (i.e. "how much") as opposed to substance.
The Minipulser can potentially work better than small ballistics if you have Ballistic Rangefinder and manually control your weapons. Although most of my testing is assuming non-Omega weapons, when I include Omega weapons into the mix for my flagship Onslaught I'll manually turn on/off the Minipulsers to ensure that they only hit against shields. Thus even though they're less efficient than the Light Needler, they make up for it by hitting shields more often, especially since they burst down a target.
The Cryoblaster works great as a finisher. It's affected by Ballistic Rangefinder, so on my flagship Onslaught and especially on Conquest (taking up that medium energy slot) it's fantastic. Back when I tested SO fleets, an SO Apogee with a Cryoblaster in its large energy slot was about as effective as a Plasma Cannon in the same slot. Now that the Apogee can have a medium energy as well as a large energy in the nose, you can mount the Cryoblaster in the medium slot and then your large energy of choice (Plasma Cannon, Autopulse, HIL, etc.) for an SO build that works pretty well.
For the Rift Torpedo Launcher, I think of it more as a weapon to instigate overloads rather than a regular damage weapon in its own right. Not only from the damage itself (which the AI will try really hard to put up shields against it), but that you can focus fire your anti-shield weapons on whichever enemy target it's approaching to drive up their flux. If the large missile slot is on a turret, I'd recommend the Reality Disruptor, but if it's on a hardpoint that doesn't face forward (i.e. such as the Conquest where the large missile slot basically faces sideways since it's a broadside ship) the Rift Torpedo works well. This is more of a situational use though.
One general note about Omega weapons is that a lot of them are burst weapons, especially regenerating missiles. This makes them very effective for phase ships, especially with Phase Anchor. So if you're using any phase ships, you should consider how you might equip them with Omega weapons, especially since Omega weapons are very limited so you'll want to put them on where they'll have the most impact on the battle.
