The ease of creating a specific sound heard on a specific song is industry leading
Interestingly enough, that was a core reason I switched from Kemper to fractal for most uses. I could get the sounds I wanted out of the fractal much faster. With Kemper, I'd either have to profile stuff myself, which wasn't the most convenient for me, or hope I'll find a profile that fits. The later was often a fruitless Pokemon hunt.
I felt the same way with tonex (which I use these days, the small one, so convenient). Other people's profiles are often a dead end with some exceptions. And even if there's good profiles to find, it typically takes me much longer than firing up the fm3 and dialing in desired tones.
But 1) this is my experience and many like you don't share it. You have a lot more success in finding profiles that fit your tastes, needs, guitars, tunings, pickups. It would be silly for me to dismiss this as irrelevant. Clearly Kemper and capture based devices work "faster" for some people, whatever the reasons are.
2) Since the time I used Kemper regularly, they've introduced liquid profiling. I don't own Kemper anymore but have access to one if I need to. I really like the combination of modelled tone stacks and profiles, especially because of the hardware EQ knobs on the toaster. Makes profiles much more flexible and I enjoy the amp-like tone stack hardware interface. And there's less of a need to shoot as many profiles as I typically would.
3) Part of the reason why I get good results with fractal as fast is because I know the amp Sims fairly well, as well as the real amps they model. That definitely took time and is easy to forget about, thinking it was always as intuitive for me as it is now -- which isn't true. And then there's also the IR hunt or dynacab tweaking.
