How does the Eclipse place among other bombers, specifically in range, speed, maneuverability, armament, survivability, role flexibility, and jump capability?

Range can be a tricky one to quantify, but basing it on duration and distance we see it as follows: Polaris, Retaliator, Harbinger, Eclipse, Gladiator. The first three all have support for long duration trips with on-board facilities while the Eclipse and Gladiator do not.
