Luckily, since this is the Red Room, we can call Nick a smacktard for posting this thread in entirely the wrong place.
V'GER PWNS ALL, I'm afraid. I could be mistaken, but I don't think I am. V'Ger can generate anything money can buy. Or take it by force!!
Eh, how about an Asgard mothership? Better weapons and systems (debatable) and intergalactic travel unlike all of the given choices (not debatable).
Can you imagine the fines you'd incur every time you simply tried to park one of those huge Destroyers??
You could steal as much as you wanted with any of those ships. It wouldn't even have to get violent. Use the transporter on the Enterprise and orbit the earth emptying bank vaults.
Good old Enterprise 1701, no bloody A, B, C, or D. Why did there need to be upgrades? It can do anything!
