If I agreed with that then I wouldn't own a QC, obviously. There's a thing or two I merely tolerate/ limp along with, but in general it gets the job done, and in most ways I prefer it, substantially, over the alternatives.
I think this is debatable. Fractal tends to move very incrementally, e.g. MkIV Turbo Plus with a Twist. Line 6 has indicated a long life cycle for HX in general. Both seem more entrenched in f/w development than bold hardware maneuvers for the moment.
It's inevitable that they'll eventually release something, but will that something speak to the differences that made me choose QC in the first place? Consider how each of these companies tend to iterate current products, and how their design philosophies have tracked over the years. Line 6 is the biggest wild card. I dig their UI/UX and their style overall. They could improve their audio engine, add some physical UI components, and really clean up. Fractal is more likely to press further into the realm of diminishing returns with mathematically perfect component modeling, maddeningly deep configuration, etc., with little concern for UX. I really admire this, but after a point, that's not where my priorities will lie.
Either way, we're talking about where the competition might be, in the future, vs. something I'm enjoying right now. :)
