Yeah but there's so much more you can do with the Helix when switching a preset or a snapshot. If you consider SC's rack rig, and all of the gizmo's .... I mean, bringing a ton of that in and out from a midi PC or CC... while at the same time turning on a particular effect on the Helix, with each of its controls changing from snapshot to snapshot, while also adjusting the threshold of a noise-gate from snapshot to snapshot, whilst also... I dunno, adjusting IEM levels and shit like that.....
It is just really damn configurable.
Fractal can do CC's and PC's from scene changes, sure. You've also got all of the modulators and the scene controllers too. But it is just a bit more finnicky, and you get less bang for your buck IMO.
