Realistically some things are just more straightforward to do on an editor regardless of what you use.
The UI on my Hotone Ampero 2 Stomp is basically a touchscreen Helix. So generally very nice to work with, but it's still easier to use the editor to build a preset from scratch because it's easier to pick models, arrange blocks, you see more parameters...
Similarly I'd rather figure out the presets for each of my Strymons (now that they added a bunch of pedals I own to their Nixie 2 editor) on the editor, rather than write them down in a notebook, even if editing a preset on the pedal itself is more pleasant.
Between Fractal and QC, there's just less need for the editor on the QC. With Fractal there are genuinely some things you cannot do without the editor, and some things that are way too cumbersome.
