100% Agree.Nobody here is saying the Kemper can't get the job done.
What is trying to be said is the Kemper does not accurately capture amps compared to the competition it now faces.
Does that mean you need to stop playing your Kemper. No. To be honest, probably 99 percent of the people on this forum (me included) have no idea what a cranked Plexi into a Marshall cab sounds like in real life. So if I buy a profile pack for a cranked Plexi into a Marshall cab, who am I to say "this doesn't sound like my amp"? The kemper is fine if you want to buy 3rd party profiles. But if you want to buy a Kemper to profile your own gear, there are currently better options out there.
I'm a Fractal user at this point, but it was mostly because the FM9 ticked all the right boxes.
FWIW I had a Tonex too, and I think the Tonex did a worse job of capturing than the Kemper did--but I know of at least one person on this forum who disagrees with me
I have almost no experience with the QC other than having seen one somewhere so that's where my commentary ends.
