If you like the whole X1 layout...
X1C is less broken than all earlier attempts at X1.
I've decided I can't enjoy the X1 layout. To me, in my personal opinion, X1 represents a de-evolution of common sensibility.
There are many many small improvements made within X1 that I would enjoy... if the track view hadn't been turned into such an inefficient use of color and space.
I have been saddened to consider that SONAR X_ may become a product line that I choose to not use.
My plan is too have a fresh hi speed computer built by Jim R. very soon and then run SONAR 8.5 with all the work arounds I already know while I learn all the other DAWs I used to think it was a luxury to not have to know about.
If anything about X1 appeals to you... then X1c is the logical choice.
all the best,
