I've owned a MacBook Pro 2016 for about 4 months now and here is my touch bar utilization:
70% Escape key
20% Audio slider
10% Brightness slider
I use Final Cut Pro X a lot too, but its touch bar enhancements are inefficient compared to just using your mouse or hot keys, so I never use them.
Yes, touch bar is a flop (to me). Otherwise, I absolutely love my MacBook Pro.
