Kemper never promised mirrored component controls.
Meanwhile every great amp that I’ve owned has been pretty much set and forget, from day one. That includes a Dumble clone + buffered effects loop with lots of knobs.
The beautiful thing about this tech is that a global set of parameters means switching between different kinds of amps and doing the very slight tweaking necessary from one venue to the next is easy and consistent.
Personally I don’t need the full sweep of every knob on every amp I use. I don’t know anyone who does.
That said, I appreciate that Fractal exists for the deep divers. Haven’t used modern Line 6, but the NDSP plugins don’t compete with the snapshot approach. The tweaking is usually about getting it to feel like what comes out of the amp just from turning it on.
Meanwhile all kinds of folks are touring MBritt snaps and doing great. Sorta like a million dudes stepping up to backline amps and killing it since the beginning of time, but better in some ways.
Anyway this argument has been going on for over a decade. Metal and prog have veered more toward modeling and everyone else-ish toward snaps. It truly doesn’t matter. No one sounds great with one or the other who wouldn’t sound great with whatever.
Meanwhile ToneX. I was listening to some free models on YouTube. This thing, maybe with five or six amps in it, on a small board with three or four other pedals, dogged software or not, still seems like the way, way best deal in town for uncompromising tones, and truly portable. At least until someone who owns a Stomp XL says or proves that those tones are just as good, and a used one wins with all of those effects and routing.
I don’t want all kinds of content in an “amp” that I’ll never use, like on modelers, but I don't agree about needing amps to profile for this kind of thing to be worth it.
If your mindset is searcher, digital will always be a fraught proposition. If not then a handful of great amps or less can make a career.
