Best/worst Civ for Random Cost Mod

Just curious about what other people's thoughts on the civs when playing random cost mod. Me and my roommate play it often and always choose random for the civs, but if you were to choose which ones would rank at the top or at the bottom.

Personally I think Khmer deserves a spot at the top as in many games you may get locked out of building something like a stable or siege workshop or worst of all farms, due to the high price of the prerequisite building, as Khmer you can blow right past it.

At the bottom is something like the Celts where the only eco bonus is really just the lumberjacks moving faster, and alot of times your siege is nearly worthless anyways because you can't afford units to protect them.
