Hydra 2, Alligator is not yet mobile enough to compensate for lack of any tanking, at least Hydra can tank a little bit. Bonus is that will let you go for Styx (Best T3 FREE engineer, Valor is prety good but cost real moneys)
Hydra 2 all the way. What makes Fed engies good is their speed, but without Energy Emitter you wont afterburn much, so Hydra 2 will just make 100 times better.
The Alligator has a shield + hull slot, the Hydra only a hull slot, so overall you get higher resistances on the Alligator, just less raw hitpoints. They are both very viable.
Personally if you go for only one of them I’d go Alligator because it opens up a lot of fun engineers and guards down the line. Ideally get both because the two engineer lines are so very different in play style, in particular once you reach tier 3.
JPHack would have flown a Fed engie like an inty. But like what Residente said, the Alligator-M isn’t mobile enough thanks to the energy issues that plague all T2 ships. So stick with the Hydra 2 if you want to not die.
Come T3, and it’s time to make the decision all over again. I have a Styx and I might pick up an Anaconda.
Now reading this i question myself again. Once i flew Emp Recons and Fed Engies (simply because they are the mainline), before i really considered factional differences. Then i switched around, because Recons have to be fast, so started leveling that, and Emp Engies are tough and heal for more, so started that line too. Now I’m not sure about the Engie line, at Styx I started to remember how fun it was to chase ships with my fast and furious Fed Engies…
As far as i can see both engineer frigates have identical healing modules?
The Styx has a +20% ship bonus. The feds only get that on the rank 12 engineer (and on the rank 2 but lol), the imperial engineers again with the Naga at rank 14.
