I very much enjoy my QC even though it's currently collecting dust (the real amps are getting used these days). There are only a few things now that really keep me in QC land:
1. PCOM. I have a ton of their plugins and like them enough that having them on the unit is great, and will get better.
2. Ease of use. It's pretty damn simple to navigate and edit from the unit. I do find that preferable to editing on the computer, especially because my computer is in a different room than my rig.
3. Cortex Cloud. It's just fun to grab a preset or capture at any time the idea strikes me. I'm often watching a video at work or away from home and think it's a cool tone and then just grab it on the spot. And it's on my QC when I fire it up. I just find that so much fun.
4. Form factor. I love the size of the QC. I get the complaints about the foot switches being a bit too close but it's fine for me at home.
That's about it really. Those things have me satisfied with it even over the Fractal. And I do love me some Fractal.
But this Stadium has me intrigued now. I suppose I could Proxy the plugin amps, which somewhat takes care of number 1.
The Stadium looks as easy to use if not even more so which should negate number 2.
It sounds like L6 is looking at some kind of easy to access eco system with all the WiFi, Bluetooth, etc. capabilities. That's still TBD of course but I think but maybe number 3 might be addressed as well. If not, it might be a worthy sacrifice for the Stadium's other features.
Finally, the Stadium Floor is larger than the QC but still smaller than FM9. And I'm moving back into a slightly bigger space in the fall so this could be fine for number 4.
I love my QC but idk...
