There are two things (other than plain old consistency) regarding realism/verisimilitude in fiction that I will argue to my dying breath:
- Magic (or its various sci-fi equivalents) existing in a setting does not rewrite the physical properties of mundane material like the human body (and the space needed for its - particularly digestive - organs) or metal, meaning an inward-pointing metal wedge on your chest (a.k.a. "boob plate") will never be anything but a suicidal health hazard, just like a remotely formfitting "ball plate" somehow nobody ever asks for would be a surefire way to get yourself emasculated and most likely bleeding out to death. A universe in which literally anything goes is worth for nothing but jokes - potentially good jokes, but only jokes nonetheless. (This also means that any and all characters can dress (and be as naked, sexy and/or promiscuous) however they want, haughty moralists be damned, but don't expect me to take someone seriously who deliberately enters combat with an exposed midriff etc., and give such "armor" fittingly terrible stats, dammit!)
- While I like the general look of the SC 'verse and can deal with a return to imperialism in the faux future, naming Earth's (largest) colony (simply) Terra is beyond stupid, based on having (and sticking to) a severe misunderstanding of the names of Constantinople in particular (and the naming of colonies throughout history in general) as well as an utter lack of common sense. (Yes, Star Citizen managed to garner itself a special place next to the general rule above, as I have yet to see that particular brand of baffling nonsense anywhere else.)
I really like the design of Elite's ships so far. They all look rugged and hard, ready to endure the hardships of space.
Many of the Star Citizen ships look trite and frail, the purpose of them seemingly being matching the colour of their pilot's purse. But I don't see that as a huge problem, as they have some pretty cool ships too, and no one is forcing me to play the less interesting ones.
I think my favourite ship in Elite in terms of looks so far is the Viper Mk II. Would also like to poke somebody's eye out with an Anaconda. In Star Citizen I admit I have a weakness for the Vanduul fighter. It doesn't look so rugged, but deadly in a lean, Bruce Lee, Kung-Fu kind of way. Cutlass, which is more bulky, is not too shabby, either.
They certainly all look more robust and for the most part also more powerful than any of Star Citizen's (non-capital) ships, but on the other hand wedges simply are pretty bland shapes, no matter how you spin it.
I like the general shape of pretty much every (human) SC ship, but something went terribly wrong with the details on almost all of them. Weapon mounts tend to look begging to break off, and way too many of them are riddled with itsy-bitsy tiny wing blade thingies that can't possibly serve any function whatsoever. Oh well, the physics engine thankfully forces them to iron out the thruster placements etc., and when in doubt, energy shields can take care of all things atmospheric entry and flight after all...
The Scythe of all things? I haven't really had a long, hard look at its current version yet, but they must have put manweeks into making that ill-shaped thing fly with their physics engine alone.
Anyway, love me some Viper Mk. II as well and keep waiting in vain to see her again.

Oh well, the Eagle Mk. II is also nice to look at in a different way, and it's not like I have a PC that can run either game yet, anyway.
I do like that contest winning '4 horsemen' ship very much. I have been following its design process from the start and it has gotten better and better. I love the detail and the powerful aggressive shape. It will be the best looking ship in SC as far as I am concerned. I will enjoy flying it.
If only it weren't for the needlessly complicated entry/exit of the bottom turret (which partly due to that doesn't cover the aft to boot) and especially those beyond ridiculous stapler thrusters...
And regarding Star Wars: There's many a reason - including believability - why I always liked the A-wing most of all.
