Gonna go FS1 and bring up the Valkryie and no Athena love? Meh, I guess not technically a fighter.
I always liked wingmen in Taurets with ample secondaries. I kinda liked it to when I could get it, good primary spread, didn't feel as heavy as an Aries. Had a helluva bite in The Procyon Insurgency with Vulcan cannons, I remember that fondly. I had to look up if it could load Maxims though... damn. I think I remember feeling like the only reason Maxims weren't compatible on this and the Perseus was balance. (Seriously, on a Serapis but not either of those?)
But when it boils down to Erinyes vs. Perseus:
Younger me would have said Erinyes. But having been on the receiving side of both ships in mods (My Brother, My Enemy... My god!) and cranking the difficulty, I'd have to say Perseus.
She's gotten me home safe more than enough times for me to vote for her in fan poll. Just a good all around ship.
