Because I'm still kicking my heels for Horizons - and I've still not quite settled into the whole faction/Navy progression thing - my port of call I try to remain at when I'm not playing, for now, is the Vonarburg Co-Operative orbiting the Earth-like planet Way, in the Wyrd system, comfortably in Federation space.
Why? 'Cause it's shiny! ;-) Elite's station interiors are generally rather gorgeous (and detailed), but they are not varied. Vonarburg was the first station that really stood out, and it felt and looked more like a place my pilot would be drawn to. Plus, I'm trying to improve standing with the Federation, so it's a functional place to be as well.
