We should be able to start a game of civ without a human controlled player and just let the AI slog it out a bunch of times. Then we could answer the debate once and for all.
WolfRevolution has an AI autoplay feature for exactly that. The turns only take as long as it takes the computer to process them. So the turns go like 1 turn/sec until about the medieval period, then it's like 1 turn/5 sec, then by renaissance it's like 1 turn/15 sec, etc.
Also, a propos the original thread:
1. Alex. CRE/AGG means he can expand, conquer, and grow pretty huge with tons of vassals.
2. Sury. Always grows huge, builds a very balanced empire, wars intelligently.
3. Zara. Ditto.
4. Joao. Will spawn overseas colonies like crazy, and techs pretty well on maps with water with his UB.
5. Justinian. Really gets cranking in the medieval era with his awesome UU.
6. Hirohito (Expansive, imperialistic), using WolfRev. Japan is actually a decent civ when give decent traits and a leader with a decent personality. Hirohito's traits are much better for both expansion and warfare than Tokugawa's, I've found.
48. Monty. Just doesn't know when to stop.
49. Mansa Musa. His presence makes the game significantly more difficult (by dramatically increasing the AI global tech rate), but he himself is rarely in a position to win. Gets beat up by the nearest warmonger before the renaissance, at the latest.
50. Wang Kon. Doesn't expand enough.
51. Sitting Bull. Gets a promising start, but then something seems to happen to his tech rate, like a giant leech has implanted its fangs into his economy, and he stays perpetually stuck in the middle ages.
52. Tokugawa. During the last game I played, declared on me with chariots...in 1600.
A.D. Meanwhile, everyone else had muskets and grens.
