Gotta say, aside from my personal history with elite, frontier and FFE, putting that aside and simply looking at the ship and station designs in the here and now, what I really enjoy is that they look robust. Like they're meant to survive in space, survive the odd scrape, and possibly outlast their pilot before being sold on second hand, scratches, scrapes and all. The scale also contributes to the sense that even most 'one-man' ships in elite could serve as something of a home.
To me, the elite universe always felt massive, disparate and often very harsh and alien in its own, ultimately futuristic way, it seemed in fact to dodge the routine transplantation of ideals, or even historical experience into the future which is so common with sci fi. There are so many worlds, and absolutely noone was hand crafting them all individually with an artistic vision, so in consequence the universe feels full of different social and cultural contexts, attitudes, experiences of life.
Were you to have them in a firefly style tv show, inevitably the individual worlds and cultures would be coloured by the vision behind the show, making the core of that show, be it characters or narrative arc or otherwise, the inexorable centre from which the elements of the universe emerge.
Elite gives you the sense, not only that you're very small in a very big universe, but that everyone else is too, and they really, really are not centred on you and what you're doing.
