No different to Clapton coils? That's not an opinion that I'd share but if you think about the progression from straight wire, through Clapton, fused Clapton, staggered fused Clapton and alien then the alien could be considered as a complex Clapton.
From my experience with these wires I follow the maxim of "complex juices benefit from complex wires". The theory being that more complex wires have a much greater surface area for the juice to evaporate on, there will also be a variation of temperature between the different wires used in its construction. I don't believe that a flat wire, with its greater surface area than a round wire, could compete on surface area or temperature variation with a complex wire like the alien.
You need to consider the atty carefully when selecting a build, in particular the heat flux within the chamber and whether the airflow can balance it ... by which I mean cool it down to get the warmth of vape that you prefer. High mass coils require higher wattages or they simply won't ramp up to temperature. It would be a mistake to put an alien build into a small chambered atty at higher wattage and with inadequate airflow; you wouldn't be able to leverage the heat flux of such a large coil mass. Even if you do ramp them up they'll likely exceed the atty's wicking capability.
In this sense an alien would be no better than a Clapton.
