Good point on the weakness of a ship that requires 5 fully operational units to make one ship. The original God Phoenix had that in a way, yet still held on to the strength of a central ship.
I don't like the pieces of the Spartan, but once it's together it looks better than the New Phoenix.
On the other hand, I like that the New Phoenix was an entity all in its own. The colors were garish and needed to go, and the nose lifting up defies the laws of physic of a ship in flight.
Sigh. No real solid good choice among them for me.
