My clips in mono into the front of amp, bear in mind.
The reverbs on QC are much more to my taste than the Helix ones. I love the Fractal ones though, especially Cumulonimbus.
I'm not that arsed about spring reverbs. I think they're generally terrible sounding, even hardware ones.
Helix doesn't have a single generation of reverbs, tho. There are three tiers:
- Legacy batch from the HD era (Available at launch 9 years ago)
- HX "ambient" ones (Available six or so years ago)
- Latest generation with "Dynamic" variants and "Hot Springs" (Available 2-3 years ago)
But the third tier smokes anything on QC. The Helix Dynamic Hall is a better spacey, ambient reverb than anything else I've heard on either device.
Spring reverb is a non-negotiable for "vintage" tones of all stripes, IMHO. It can be a lot more than drippy surf/spy pablum. It's great for subtly giving a lived-in feel to funk/jazz/blues tones.
