The thing currently comes within a gnat's whisker of being outgunned by the Sharoos which is a whole PL lower. The Neroon needs a definite boost to firepower and survivability before I would consider taking one.
Observation: The Sharoos is nothing more than a gun platform. The Neroon is a true fleet flagship.
It's hardly a 'gnat's whisker'. The Neroon's forward guns rack up an extra 30% damage* thanks to
triple damage lasers and
twin-linked fusion cannon, and that's the best that the Sharoos does - when looking at the broadside weapons it's closer to double the punch**.
The Sharoos does have all-round lasers, but the Neroon has no weaker arcs; it has ship-killing firepower in every direction. The extra range of the improved lasers is also nice, but less critical because you really, really want to be in a position to use the battery of a dozen twin-linked fusion guns as well.
Also - carrier role. The Sharoos has 1 flyer flight. The Neroon has 2, 8 nials,
carrier 4,
fleet carrier and
command +2, or - to put it another way - it's got a Morshin-class carrier welded onto the side. Which is pretty much the same as the increase in hit points.
* Average damage Sharoos 22, Neroon 29
