Frigate/Destroyer person here, the best things always come in little packages.
There's a couple great ships and a few hit-and-miss ships; at least in combat. The Pala is great as a support frigate with decent cargo capacity, burn 10, and the M-Uni slot, but the Farin lacks the Flux stats to utilize both its shield and weapons - though it's a freighter so eh.
The Rastrum is a anvil, a lot tougher to kill than an enforcer; but has fewer weapons. The borer drones are of rather dubious value though. I believe you said you're revamped it so I'll hold on judging.
The Mantarn is a bit like a mini-apogee, decent all around ship. Feels a bit under-gunned though; though it's also going through reconstruction.
I can't really find a use for the Acutor, it feels like it tries to do too much; though I suppose that's kind of the point. The Repair apparatus only appears to speed-up repairs, not actually reduce their cost; which suffers from the issue its construction rig mounted variant does. On the other hand, it is the cheapest capship to field, supply-wise.
The fighters are significantly better. The Negl is a better broadsword, the Golgata is a dagger on steroids, and the grudiver leaves mining pods in the dust. The Obex... not so much; for starters, I don't think it even has enough flux to fire its mining blaster.
Ship choice is still pretty bare. You'll probably want a flight-deck alternative to the Acutor, but doing so pretty much dooms it to the back-end of the ship lineup. They lack a dedicated hauler/tanker. And it relies on fighters to deal the brunt of its damage.
I'd certainly like to see more mining weapons, you've got the mining laser and mining blaster and that seems to be it.
