It'd be better if the OS wasn't garbage to be honest. Sierra and High Sierra, either through poor design or planned obsolescence has entirely soured my organization to the benefits of the MBP. Between that and the incessantly bad consumer garbage they push out with the OS, it's just not worth it.
It was fine for me. Same mbp retina 8gb system incrementally updated since 10.9.5. Took a while but munki installed the update without issue.
