The ship battles vs bulletsponges are neither intense nor difficult but rather a display of plinking away at enemies with peashooters. Aka a snorefest. And totally not worth doing.
Maybe if you're taking blow for blow in a fat engineered ship. But I'm having to maneuver and evade; and when I get their shields down then try to dig into their hull as much as possible before my shields go down; then use the asteroids for cover until my shields come up, or risk digging in some more and trying to evade, then their shields come back. Both of our shields will go down multiple times in a single battle. With fixed weapons they can't tank that much, it's mostly a case of how much are they evading - smaller targets are quite good at evading fixed weapons. With larger targets they can tank more but that's to be expected. In any case the battles are very dynamic and not at all boring compared to engineered combat. I spent enough time face tanking CG pirates in my engineered anaconda to know the difference.
