I got a handful of CCUs for the ES and MR variants using store credit. I might get a couple for the CL variant as well after the 24 hours delay on melting will expire.
When I saw the interiors, I immediately thought about the Corsair. now, the Corsair is 55 meters long, which is longer than the Zeus 2 at 46 meters (source: brochures on the RSI website), so the Zeus is not quite that. And the ship matrix on the website says that the Constellation series are all 61 meters long. And the Mercury is also longer, at 56 meters. The Zeus is longer than the Cutlass however, the latter being 36 meters long if you trust the ship matrix. And the Freelancer series are all 38 meters long.
I was quite hard-pressed to find a ship of comparable length to the Zeus 2, but I did find one... the Spirit series (which some might compare to the Cutlass rather than anything else).
It seems the Zeus is either almost, or sort of, in a league of its own. There aren't too many ships intended for a crew of 3. the ship matrix says that the MSR is for 3, but it definitely has more than 3 stations. the Vulcan is under 40 meters according to the ship matrix. But the price range for the Zeus seems to be in line with the Spirit and Cutlass series, despite being bigger. The Zeus 2 CL has a lot more cargo space (128) than the Spirit C1 (48). and the ES variant (32) of the Zeus has a bit less than the S-C1. The Corsair has 72 SCU.
So honestly, I don't think the Zeus really properly compares to any other ship in the matrix. There are almost no other ships of comparable length, crew size or cargo space.
