I still like everyone should ask themselves the important question: "Do I want/need a software editor so bad that I will accept that Kemper stops developing the KPA (no new fx, improved UI, improved midi spec...) for a year or two?
I'll answer. Yes, 100% yes.
I'll also answer another question posed earlier, which was to name specifics.
Kemper has done a wonderful job with recent OS upgrades. Morphing is pretty cool and the new delays are beautiful. I have tons more amps at my personal disposal for the Kemper than I would have for any other option. I don't need much in terms of drives. The new delays are awesome. The reverbs are fine. Outside of better reverbs and drives, I'd pretty pretty satisfied for a long time in terms of in-the-box capabilities.
Here's the deal, for me, anyhow. I have had a Kemper & Kemper Foot Controller for a year, and an AX8 for 6 months or so. The AX8 naturally stole attention as the new, shiny thing. After the shininess wore off, I've stuck with the AX8.
The difference? Editor.
I work at a desk with a computer, and with a guitar strapped on, and using a keyboard and mouse is easier than twisting knobs and mashing buttons. It just is. For me, anyhow.
I am also weary of any component that wears out. I'm convinced that long term, after a few years of knob twisting, I will need to replace Kemper components. Feel free to enlighten me if I should not be concerned about this.
If you are going to tell me to stop bitching about twisting knobs and just play, that's not an answer. I happen to like digging into options and creating patches and my weekly set list many times includes 2-3 new songs. Creating new stuff is a part of what this technology is all about.
Maybe I'd twist less knobs and push less buttons if I spent more time with the Kemper to memorize where everything is.
That all said, to get what I need done, the lack of an editor is the reason I use my Fractal gear over my Kemper gear, and I believe an editor would draw me back to the Kemper.
