Yes.... all of the above. I find that MOST people who have used both consider the KPA easier to obtain a specific tone for a specific song on...... or to get a specific tone they have thought up in their head. Again, not saying the Axe doesn't let you get there, just takes more work and time.
Just another point ......
The Fractal editor is indeed very easy to route and use modules for those who understand routing and modules well. The KPA lends itself to people who spent a lifetime running tube amp rigs and pedal boards.
Creating a specific tone via profiling requires having analog (or digital, ok) gear to use. Fractal includes a lot of amp sims. I'm not sure it's easier for the average user to profile an amp compared to tweaking in axe fx... Unless maybe we compare some very complex tweaks vs the most simple profiling scenario perhaps, assuming gear is present?
