In my personal experience the best purchases so far are the EC Cap increase, +100 Doff Slots (I do doffs a lot and I find 200 to be satisfactory) and the extra character slots.
I send DOffs off on assignments whenever possible, and 200 works out. If I was stuck with 100, I think I'd run out of room for DOffs that are necessary for assignments, and spares to upgrade with the 5-to-1 assignments.

I noticed that the Odyssey is available at Fleet shipyards, but it's the basic one - not any of the three that can be purchased. I see that it's short one console slot, dunno about the stats.
