There's no denying the Cortex profiles (whoops 'captures') well, but I'm much more concerned how if plays under the fingers.
I love my Kemper and I think its the stand out piece of guitar equipment I own, but as close as it might be to a tube amp, a tube amp it aint.
For me this is where the most important comparison between the KPA and Cortex will come into play and what I'm most intrigued about.
This'll be subjective of course, but individually we'll only know for sure if we get to try the new kid out, and are honest with ourselves.
I reckon Kemper already have a head start on this after introducing the excellent Kabinet, so roll the dice......
