oddly enough I have a system76 ibex pro and a 2015 macbook pro 13". I'm almost a year into switching over. (Everything except lightroom). The system76 is much bigger, clunkier and not as well built. But honestly its fine, the software is updated frequently and besides a couple of times where the keyboard didn't come back after sleep the systm76 has been a trooper (sleep awake cycle brought it back).

I enjoy this machine and would buy another.
