Ok, I thought they were quite similar. So, would Sins be more in the Homeworld end of the simulation specrum?
I'd say a bit more sim-esque than Homeworld, but the focus on strategy is similar.
With Sins you're working with a far larger theatre of war though, across multiple planetary gravity wells (which are the buildable locations, connected by jump-lanes).
You also have some planetary development, although nowhere near as detailed as GalCiv2 does. It's mostly upgrades to income, planetary hitpoints (for bombardment resistance) and slots for support structures and defensive orbitals.
Managing construction on such a large scale can be difficult in an RTS, which is where the Empire Tree comes in, it gives you an "at-a-glance" overview of every world you hold, it's orbital structures and vessels present in its gravity well. Probably one of the best features of the game, given it's scope.
With the "entrenchment" micro-expansion you also add a massive battlestation to that list, which is great for holding choke-points, as it can keep entire fleets busy on its own, especially supported by the normal defensive infrastructure.
