Should Linux users consider buying a Mac? No. Why? Because of the pyramids in Egypt*.
... I feel that I may need to back up here a bit to explain that odd pairing of answer to question.
When MacOS was still relatively new, Apple started taking out full page ads in magazines that UNIX users would often read touting how it was the user friendly UNIX ... but those magazines were actually read, by that point in time, mostly by Linux folk.
In the years since, I've seen many Free software using folk start using Apple products because, to them, they were one or more of the following: usable, pretty/stylish, trendy.
I remember one pub argument from many years with my friend and fellow Free software hacker +Mirko Boehm
about the relative merits of Mac, wherein he espoused how great it was from a technology POV and how Linux was unlikely to break into the masses like MacOS was looking to do. My counter point was that none of that mattered because of the freedom aspect, and that if we focused on MacOS as the saviour of UNIX-like operating systems for the masses we'd just be shifting influence from one closed company (Microsoft) to another (Apple) while undermining the eyeballs and fingers that should be improving the Free software stacks on operating systems such as Linux. We parted ways that evening still disagreeing .. but I remember the discussion vividly, down to the wood the bar was made of.
So when I read articles like the one linked below, I feel we still haven't quite figured it out.
It is not about utility first, it is about freedom first. Freedom informs utility, though it may take longer to do so.
Think of every great technology from the past that was proprietary whose company changed direction or simply folded up shop. Each of those technologies was either freed and allowed to live on or disappeared into the aether. No matter how good a proprietary technology is, its life span is limited by its lack of freedom.
While every Free/Libre technology may not live forever, this is not a property of it being free. An inevitable end point to the life of proprietary technologies is, indeed, a property of their lack of freedom.
So the question becomes not is the audio stack on Linux good enough for video editing, but do we wish to have a tool for video editing today that will not exist by the time our children are grown up. Or would we rather have a great tool that matures like fine wine and cheese does and which we can enjoy for a lifetime.
Example: EMACS and vi. Those two tools are, in computing industry terms, ancient. Yet they are widely used and are both fantastic tools. (Though every programmer truly worth their salt knows that vim is the better of them ... </flamebait> ;)
During the time EMACS and vi have flourished endlessly, we've witnessed the coming and going and a remarkable number of proprietary text editing tools. Many of those tools were better than EMACS and vi were in their infancy, but that certainly did not save them.
This pattern repeats in many other software categories.
So if we fickle-minded, attention-span-challenged, shiny-things-distract-us-like-a-3-year-old-baboon technology enthusiasts could learn from history and stick to the tools that promise longevity, we would find that problems in the Linux audio stack (e.g.) would resolve themselves quicker and we'd have something wonderful to pass on to both our older future selves as well as the generations that will follow us.
This, by the way, is yet another product of the practice of thinking not only of right now but casting our eyes forward into the middle future while thinking of the right now. If that seems unrealistic to you (perhaps because people seem not to do so), consider that we humans have a couple hundred thousand years of history stretching behind us, admittedly with most of the interesting parts being in the last ten thousand or so. If we are the product of an exciting adventure stretched out over 10,000 years of unbroken, if complex and not always pleasant, narrative, it becomes obvious and evident that viewing our current actions within the context of the next measly ten or twenty years should be no great stretch. Being informed of our shared deep past, we begin to understand that "the now" is measured in decades not months or years. And so many people in various disciplines have been shifting their eyes upwards from their feet to the horizon.
When we do so with technology, it is self-evident that technologies based in freedom are the only investment worth making.
So, no, you shouldn't consider buying a Mac. Because the pyramids*.
