Avengers are actually better at hull damage than Prometheus O or R, in terms of damage-per-second. I prefer the Avenger.
(The S-variant owns, but it's an apples-and-oranges thing, since the S is 2367 tech and the other two came much earlier.)
Pros: Good fire rate (0.25), good hull damage, small energy usage
Cons: Mediocre shield damage
Pros: Good hull and shield damage
Cons: Mediocre fire rate (0.3)
Pros: Slightly better shield damage than Prom O, with 300m more range
Cons: More energy usage, poor fire rate (0.40).
Pros: Insane shield damage, good hull damage
Cons: High energy usage, poor fire rate (0.40), poor compatibility.
Oh, sorry. The Prom R I describe is from my
TBLs, not the craptacular one that most people insist on not balancing.
