Both are vessels that can be used on the way to endgame, from levels 31 to 51 if the player chooses to pick them up once turning Captain, keep with it during Rear Admiral ranks (its tier 4.5 power makes it tolerable to keep around) until access is gained for Retrofits at level 51 where the player can choose to retain the skin. That, and the console provided, gives excellent all-around value to those whom purchase them.
I think the way they are presented in the C-Store is flattering, something that's not the norm from what I've seen in the past. They look slick, new, and encourage the sense that we are 30 years in the future of ST:Nemesis.
I won't be buying them. I'm not invested enough in the poorly-maneuverable exploration cruisers or the KDF, but I'm going to enjoy seeing them around. I hope some NPC ships we encounter will have their guise. I'd also add that the Vor'Kang's beautiful klingon-feeling design almost makes me want to captain it as a Klingon. Just, not quite... but if I had a Klingon character, I'd want it.
I'm finally going to do the grind and get my KDF toon up to Captain just so I can fly this ship around. While a few of the Klingon ships say to me: yeah that's probably what that would look like down the line, this one screams Heg'lu meh Qaq jajvam!
Its not just a skin and a console, its a tier 4 ship with superior stats.
Unless you just NEED to have it now, I don't see why you'd buy it now though, given the updated economy coming "soon" where this should be attainable via your normal upgrade schedule, or at least for ingame currency, not to mention the C-Store price changes and the subscriber stipend.
If we knew more about the ships coming down the line and the plans for them, we could be consumers making an informed decision.
