Honestly... None of them.
Don't mistake me, that pimp variant is very good, better than the original. That kitbashed one too, is impressive as well despite that strange Tri-tachyon feel. But i kinda like the old, functional and soulless SCY metal boxes.
It's true, it could be better, that dry aesthetic we're used to could be improved into something sexier. But SCY is already one of the best and most complete mods around, does it really needs that?
And more importantly, i'd be more hype about a campaign integration of Seeker first, even a basic one, than a lifting of SCY.
