Indeed, the Mechanicus is getting more material published on them, perhaps It'd be good to play as the Mechanicus especially when the new fluff is released.

And the Mechanicus offers you a choice, as you can still play with Combat Servitors, Skitarii, and all other manner of machines if you choose the Dark Mechanicus you'd have even nicer units availible such as daemon engines.
