If you really like macOS, the Hackintosh route is keeping quite stable these days. The NUCs have such generic hardware that there is practically no .kext fiddling and with the Clover bootloader any adjustments that need to happen are a breeze. Up until recently graphics issues with my Radeon cards kept me from using macOS full-time on my rig, needing major backflips to get acceleration and full resolution support working reliably. Now it's just a zero-config .kext drop in, whereas the common suggestion was just to get an Nvidia GPU or live with the on-board graphics. Even better is the recent work to support AMD CPUs. Dev interest in getting them supported fell off quite a bit since the Leopard and Snow Leopard days but it's seeing a strong resurgence now. Just to put things in a more perspective, though I have a few years of effort put into understanding what goes into Hackintoshing my latest effort in getting High Sierra working on an APFS drive took less than an hour overall. Whereas before, it was a weekend job. Better still, if you're in the market to buy new, the common build guides are bullet-proof. Basically anything from Intel (like Ethernet controllers) works without any issues and has for some time. Most hardware that looks something like an iMac or Mac Pro will be reliable and trouble-free, especially if you hang back a dot release or two.
