Debatable.. Certainly the most expensive.
Macs are far better than any Windows/linux prebuilt i've ever seen.
Of course custom built pcs are the best thing there is but when it comes to prebuilts, Apple is the obvious choice.
And using the same drives, CPU, graphics...
Apple vs Windows is more a decision of what ecosystem you want to buy into.
Software specifically built for the hardware, best operating system there is (yes, I know it's an opinion), great battery life, no forced updates, iWork for free, GarageBand and iMovie for free, best trackpads ever put on a laptop (force touch), best speakers on any laptop and many more reasons.
As someone who uses both my custom built windows pc and a mbp daily I can say i'd much rather be using macOS than Windows.
