I'm also a big fan of the Surface (and Windows 10, too!). We went from Mac to Windows and I have no regrets. (It was the desktop / high-end that pushed me over. No good "pro" option on the desktop.)
Exactly right. We do accurate-color work so I need a wide-gamut monitor I can calibrate. And we need NVidia "Pro" cards (with FP16 full-speed) support. The Mac "faithful" will tell you can can jerry-rig a side-car box and run your GPU cards over USB-C, but that's flakey and slow.
