I’m considering setting up one of these in a low sec system, because the system has no stations in it, and it has good planets for Planetary Interaction. (Mostly just want a place to stow my goods, so I don’t have to make lots of trips in and out.)
It looks like the only difference for efficiency between the two is the 3% vs 4% Isk cost of starting projects.
The difference it manufacturing time bonuses (15% vs 20%) probably won’t affect me very much because I’m just too new at it to keep my jobs chained well enough to benefit from it.
I’m kind of worried about someone coming along and blowing it up, although I’ve seen some pretty small (probably 1 player) corps have structures in the system. So they must not be getting blown up too often.
