I believe the Scyk will be the quiet breakout of the wave. It will do so based on it's customization, just like the sales brochure says. It is by far the most inexpensive way to add recurring stress or ion effects, a follow up crit, or many of the other niche effects that come on secondary weapons.
Like the Headhunter, it won't be the centerpiece of a list. But like the Headhunter, it is the cheapest way to fill a particular need, and the variety of needs it can fill will see one or two of these fitting in to a lot of lists.
