The Dracite is more pricey than the Kabal Haemonculus option, but the Dracite will also be more useful on the turn the Portals open than a Haemonculus would. With a charge range of 18+d6", the Dracite can rush into an assault along with the units emerging from the Portal - as can any surviving Warp Beasts, and the Archite (assuming they aren't already chewing up nearby enemy units).
