A fair question indeed; I'm primarily a photo and video editor so with the exception of FCPX, which I do use in addition to Premiere Pro CC and Resolve, most of my applications are cross platform. At work I do have a Windows 7 box, but I primarily use the office's maxed out 2012 27" iMac. I have always preferred MacOS to Windows and while it's taking some getting used to with Windows 10, I think I can manage. The Alienware 13(Kaby Lake)with OLED display, 16GB Ram, GTX1060 w/6GB, and 1TB M.2 nvme was roughly $2300; While not necessarily a direct competitor considering the screen size, the 15" MBP Tb w/1TB and the 460 is $3500.
I would have loved to have purchased a MacBook Pro but I really needed a personal computer now(and didn't want to pay $3500 for underwhelming specs) and after surveying the landscape(XPS15, Razer Blade, etc., I opted for the Alienware 13 r3; My previous computer a 2009 4,1 Mac Pro finally gave up the ghost about a year ago, and I had upgraded the processors twice, maxed out the RAM and, threw in a flashed MVC GTX980 in there. It was a powerful computer then and would have continued to have been for me for a few more years had the power supply(at the very least) not died.
One thing I've always appreciated with Apple computers is(for me anyways) they literally "just work" right out of the box. This Alienware crashed on me during the setup and registration process and what was most annoying was the Samsung 960EVO 1TB M.2 drive that I purchased separately was not being recognized as a volume in Windows 10; I could see it in the Device Manager, but nothing in the File Explorer and I could not install the appropriate drivers and Magician software from Samsung. Three hours later and several re-seating attempts of the drive, I discovered, after pouring through the ole interwebs, Dell has the machine drive slots(there's two in there btw) configured as RAID even if the machine doesn't ship with a second M.2 drive; I had to go into the BIOS and change that out to ACHI and I was finally able to install the driver and software. Absolutely maddening.
