Practically I did find the QC likely has 50% more DSP than the Helix, which is more than I'd ever need. Enough to make a preset that's too big to deal with anyways. Cool thing with captures is that they are lower DSP so you can run even more of them. Again, not sure how practical that is, but I have run presets with dual amp captures and 3-4 drive pedal captures out front, with lots of DSP for other effects.
