1. Monte Carlo Freeport.
2. Ames Research Station.
3. Fort Bush. Yeah. I said it. Fort Bush.
Edit: Forgot the "why".
1. Coolest looking station in Gallia by far with the snazziest bit of history.
2. Being in the middle of a dark matter storm run by ride-or-die storm chaser scientists is cool as heck for Ames. I like all the activity around it as well, showing the effort that goes into keeping life moving in near-impossible conditions.
3. I just have a soft spot for Bush and its info card, as the center of early Sirian exploration and a meeting point for traders from all over the Houses. Manhattan orbit might be considered the true center of Sirius, and people might congregate on Trenton, but Fort Bush comes off to me as the humble port of call for the honest working spacer.
