My perspective differs from Jarno’s.
I have used Macs since 1991, and used PCs before that. I continue to use my 2011 Macbook, but my desktop and main machine is Windows 10 for purely economical reasons. The difference in price per processing power is less than it used to be however. I was running it as a Hackintosh until last year, and upgrading to a newer operating system would have required buying some components, or many hours of trouble-shooting, so I bought a copy of Windows 8.1 and have been using Windows since then.
The best thing about Mac is that they have figured out a way to get many developers to use, or appear to use, the same conventions in different programs. Things like option-clicking the close box of a window to close all windows of that program, and the fact the opt-tab cycles not through all windows of every running app, but just through each running app, are a couple examples that require more work to setup, or cannot be setup on Windows.
The uniformity and stability is worth the money if you can afford it, and the more expensive machines do last a long time. There are many people using 2008 and 2010 Mac desktop machines still. There are also some very elegant functions such as Spotlight search, this search system is fast, remembers your last search, so reduces clicking and typing. Mac has an advanced ergonomic feel compared to Windows. The command line interface on Mac is very good, shares many commands with Unix, (really is a type of Unix) using this is a pleasure, and it is easy to learn the basics.
Windows is more configurable, though less now than in the XP days. To really get the best bang for your buck on PCs you would have to build one yourself, and many folks can’t be bothered.
So for many folks Mac fits the bill better than Windows.
