I've been running macOS on both my XPS 15 (9550) and desktop (Haswell i3 based w/ Nvidia graphics). The experience is good on both systems but they definitely have their caveats.
The XPS is probably the most positive experience thus far, it'ss a 9550 with i7/16GB RAM/1TB NVMe/GTX 960/4K. It's currently running Mojave 10.14.3, everything except the SD Card reader and Nvidia GPU work (including the touchscreen, WiFi OOTB, Bluetooth, etc.). The GPU really isn't a problem, Intel graphics work with full acceleration and anything GPU-heavy gets done on the desktop. Helps with battery life too; my system's battery health is down to ~45% but I can still squeeze out a good 4 hours from it. It's not very well supported, you really gotta stay on top of updates and be ready to fix what breaks, but when it's running it's a dream to use.
The desktop on the other hand is a completely different beast. It's got an i3-4150/8GB RAM/GTX 980 and currently running High Sierra 10.13.6 (because of a lack on Nvidia drivers in Mojave). Getting it setup was a little bit of work, the WiFi/Bluetooth card needed an enabler kext and audio needs a bootloader tweak to work, otherwise it's functionally indestinguishable to a legitimate Mac; It can even be updated through the Mac App Store, iCloud/iMessage works, Handoff works.
