From an exterior standpoint I prefer Columbia
. The bluish coloring and the larger deflector dish look so much better than the NX-01's reddish hull and laughably tiny dish, IMO. I thought the designers did a great job of taking the "we want the Akira!
" declaration from on high and turning it into something kind of rugged and primitive. My only nitpick would be to smooth out those bumps on the hull (located on either side of the bridge) that extend back into the nacelles, which I think is what made it look more like the Akira
than anything else.
