Omen seems built for support. I tried to use it as an assault ship long ago when skills were stronger, but it is too awkward. It could be done, just... awkward. No point trying to force Omen into a typical beatstick. It would be like trying to force Monitor to do anything beyond being a meat shield.
Tempest seems okay. It can support a medium weapon, or at least escape. With speed and drones, seems worth its price.
Scarab does not pull its weight. It used to during 0.7.2, but not anymore. Effectively, it is probably a 5 or 6 DP ship. Temporal Shell does not help enough. After using it, it can only use one or two small guns. More than that and flux will build up to max before the shell times out. (Venting breaks the shell.) Similar problem of Accelerated Ammo Feeder before it got half flux cost discount.
Hyperion is too expensive. By the time I kill a cruiser, PPT expires and it is time to retreat. Just one step away from being a glass sword, without the power. AI cannot use it effectively. As it is, maybe worth 12 DP.
I kind of wish Shrike and Shrike (P) merged into one ship. (Pirates have few other ships that are identical to normal aside from paint job.) It gets annoying being locked into Sabot Pod with normal Shrike if I want it to kill stuff. Shrike (P) has annoyingly low OP.
Odyssey with combat skills is strong, but it has to specialize. If I outfit it like a conventional ship, it stinks and gets killed. As for being the best, not sure. It can avoid stuff, but killing things before PPT runs out without making a mistake can be tricky. It can do what playership Conquest does faster and with less damage taken. Meanwhile, sometimes Paragon can flatten the enemy quickly (that other capitals need finesse to deal with) while other times, one mistake and it goes down like Onslaught or Conquest. Odyssey can use large energy weapons, and the gap between energy and ballistics is less for large mounts. Without skills, I do not know how good Odyssey is compared to others. AI cannot use loadouts that are devastating under player control. Plasma Odyssey piloted by AI will burn into a mob to die. AI Odyssey probably needs that shotgun build.
Paragon seems a bit overpriced. It is good in player hands, but AI does not seem do much better with it than with Onslaught or Conquest no matter what I put on it. Under AI control, it seems to perform like a 50 DP ship. Player might make it worth 60 DP under ideal conditions.
Aurora, I'm not sure if it's good enough for its cost, or not. I typically use it as a missile cruiser, with missiles in question being sabots, and while it's great for bullying smaller ships, it typically has to dump all the missiles to tackle same size opponents or even bigger. I should take it for some AI testing, since borderline all of my experience with it is with my own piloting, but unfortunately I'm very short on time currently and I have no idea when will that happen. Odyssey is in a similar spot, since... Well, actually, it's absurdly rare and I have no idea how competitive it is lately, in comparison to Conquest. I liked the ship a lot, once, but carrier rework made flying it busier than previously.
Under player control, it can solo a mob of smaller ships, that other lesser cruisers cannot do, but it requires some finesse or else Aurora will take too much damage or die from one mistake. Doom or a capital can just flatten them with less finesse required for only a few more OP. Aurora under AI control is incompetent. Meanwhile, AI can use Doom well, and can use a capital more easily than Aurora. Aurora is probably worth 25 to 27 DP.
Without missiles, Aurora needs to throw everything into vents and hullmods that improve flux stats and shields to win flux wars against equal opponents or mobs. Does not matter if it is two heavy blasters in turrets, or a mix of (IR) pulse lasers and a heavy blaster or ion pulser in the hardpoint.
The nice thing about Conquest is both player and AI can use it. It can (try to) do what Odyssey can do, but it takes a bit longer and will probably take more damage. So it is not as good as skilled Odyssey under player control, but at least the AI can pilot Conquest well enough and not do stupid things.
But we might notice that these are not problems with energy weapons these are problems with like... 2 frigates maybe.
Aurora too, but that could be fixed by lowering the DP cost closer to other cruisers.
Problems with energy weapons is not for high-tech alone, but also midline. There are not many weapons I want to use over ballistics on many midline ships.
