well, technically Kemper is just a cloner not and advance deep editing ass kicking amp modeler!
Kemper does let you deep edit if you want to:
Axe FX has more deep editing functions for sure but that doesn't mean Kemper lacks them at all. Kemper has less of it because that's how it works. When you own a dual recto, you don't try to make it sound like a 5150, you go and buy a 5150 instead. Same with Kemper as a cloner. If you wan't 5150 sound you just load an 5150 profile instead of tweaking that recto profile into a 5150. That's why Kemper doesn't offer deep editing parameters like resistor brand or pcb thickness, etc.
