My suspicion is that it is to do with the set of third party software and peripherals used.
In my case, that’s a 2nd gen 15” touchbar MacBook Pro, a 15” 2015 MacBook Pro, and a Skylake i7 hackintosh tower. I use Asus and Dell monitors and stick to first party or Mac exclusive third party software wherever possible. All three give me little or no trouble with high sierra... reboots are infrequent (1-2 per month, sometimes less) and are usually done to install updates or boot into windows.
