I have a Dell U3415W w/ a second 24" 1080 for my desktop, and to be honest, I'm often more focused and comfortable working on my 13" MBP in a comfortable chair instead.

Xcode is far better on the desktop but for terminal + vim + broswer type work, the laptop screen is perfectly reasonable.

As for using OSX, I've just gotten comfortable with it. I never have to fiddle anymore. I always wait to upgrade OS's and it generally just stays out of my way. Windows is annoying and I haven't found a comparable fussless linux laptop yet (and I'm actively looking because I won't be able to keep avoiding that stupid touchbar).
