As far as workflow and window management goes, OS X is a good half decade behind Windows, and in a lot of system-level ways, it feels a decade behind. I use a MBP Retina at work, and it feels primitive compared to Windows 10, which I use everywhere else. Everywhere else, I'm doing audio, video, and photo editing though. If your day to day work is more CLI and *nix oriented, I can understand the appeal of OSX... although some of the variations of Vim that I see people running might as well be GUIs.
