Aye, I thought you were looking more towards an awake expander SC. It would seem that overall the Cyclops is going to be the better choice, since he is FR for the scorching heat of his dominion. Likewise, that's what the Warlock has over the Enchantress. Though with the rainbow chassis, they are less often committed to real combat I suppose, sitting safely back doing summons and globals, rather than risking it all on random luck with 10hp.
But all things considered, like I was saying, I don't think they really -need- an awake SC. I like the Fountain of Blood, as I feel the really strong scales may not have you expanding quite as quickly as a Clops, but that the income and resources will set you up for solid mid game troop and mage recruitment, and then the dousing bonus gives you a solid benefit to your late game position. Obviously Abysian Infantry aren't the optimal fastest expanders available, but they are so survivable that neither are they the slowest. I think for optimization then, the high scales with dousing bonus will add the most power through the duration of the game. Bearing in mind that it seems the general feeling towards Abysia is that they start out "fairly strong" (not exceedingly so), and slowly lose relevance as the game progresses, so I really feel that giving up a little at the start may be the key to a better shot at victory in the end.
Though I have to say, having to choose between 6D/6B or 6E/6B on the Fountain is not an easy task..... For 24 more points (maybe drop to Dom6) the Fountain can go 4E/4D/6B. In this case I'd think that the reinvig would be worth the lower Affliction bonus. Though at that point, might swap it to 4E/4S/6B. If you've Arcane Probed everything by year 3, you could use Acashic Record on your wastes and swamps for bulk gems to alchemize into pearls, if nothing else.
I will admit however, I have a soft spot for the Cyclops, he was my first successful SC.
