The Kronos is t heavy at all compared to Motifs. And I think user friendly comes down to user experience and preference. I can use any of them. It's a matter of spending time with them.
I sold my Kronos only to find out the user memory space on the Montage M is actually low.. If you are serious with loading in LOTS of multisamples you need a streaming synth like the Kronos or MPC Keys. Put in a 2TB ssd and your golden. Also don't forget you have 8 parts and not 16 to load in your sound. Part 9 to 16 are for external triggering only! You can only get around this by stacking elements, but it takes a lot of time. I won't say i regret getting the M, it sounds amazing, but in some specific cases it's quite limiting.
