Apple did have impressive build quality, but those days are long gone. I can run happily on a MBP from a few years ago, whereas the newer ones have had numerous issues.

In terms of overall quality, I'd say that MBP is now behind some of the other high-end devices. The Surface Book knocks the latest MBP versions out of the water in every department, except for the track pad. It's not difficult to argue that the keyboard, screen, durability, or even the OS is superior to Apple's (current) offering.
