Yes, it's absolutely worth it.
The Aconda is big and kinda sluggish, it's true. But thanks to the FSS, I can park near the star and I'll only need to approach a planet if I find something interesting and I want a closer look with the probes.
There are upsides to flying a ship that size. She's durable for a start, and she'll fit all the modules you could want to take. I'm carrying two fighters, four SRVs, two AFMUs, a repair limpet controller and a MASSIVE (1245 T/s) fuel scoop, and she
still has a 60 light year jump range, so she's very fast when it comes to crossing distance. I'm gonna be spending a while over at the far side of the galaxy again so a "kitchen sink" approach works well for me, and the Anaconda has room for everything.
I've only been out on my expedition since very early Christmas morning, and we've already covered over 30KLy. Tonight we leave the Errant Marches and we're looking to find a way into the Aquila Halo.
So yes, absolutely. The anaconda is a resounding yes vote from me.
