I think one area of disagreement may be whether the question is primarily about an operating system or possibly whether an operating system constitutes "music software".
My reading of it could be analogous to a question like:
I have 20 different synthesizers and I'm about to move to Japan from the USA. I've heard many electronics will work on Japanese power but some of them won't. What problems might I encounter with my synthesizers in Japan?
Even though the concern is regarding the synthesizers, the question is about electrical power. Yes, maybe there are people here who know a lot about different synthesizers and who know a lot about power and maybe even have moved a bunch of synthesizers from the USA to Japan themselves. None of that changes that the questions is about electrical power.
Similarly, this question was about an operating system. Even though the asker uses many music-related applications that depend on the operating system, IMHO the operating system itself is not a music application. Many of us may use many music applications on the operating systems in question and have some knowledge, but that still doesn't change what the question is about.
Now, let's assume for a moment that the question is actually on topic. As far as I can see, there is only one way to answer it correctly, in a similar way to the sample question I came up with above. The only way to answer it would be to get a complete list of all the audio applications the asker is using and then attempt to run down how "stable" (which again, is a word with no clear meaning in this context - and my day job is in IT) each application would be expected to be on each operating system the asker is considering. Just like one would have to check the power requirements and compatibility for each of the 20 synthesizers to know whether it will work in Japan in our example question.
To me, that's too broad. And even if it weren't too broad, we still don't have a list of all the music software the asker would want to use, so we have "unclear what you're asking" (essentially).
Ok, now let's suppose that we've decided it's on-topic, it's (somehow) not too broad and we have a complete list of all the music software and hardware the asker wants to use and we have agreed on what it means to be "stable" (never crashes? only crashes once a year? what constitutes a crash? what about latency?), and somehow magically someone has gone to all the support web sites for all the software and hardware and vetted the eventual operating system and figured out which components will match the stability criteria we have established for which possible operating systems and has posted a textbook-sized answer that satisfies the asker.
There's no way someone isn't going to also answer with "No, that whole textbook sized answer is wrong because I did this with my computer and it blew up/works great/whatever" and now it's primarily opinion-based! Really, it would end up being primarily personal-experience based, but for our purposes they amount to the same thing: a big argument over anecdotal evidence.
Finally, if someone can actually provide a solid, supported, effective answer to this question, then they would have reasonable standing to argue to re-open and they would be able to explain exactly why it's:
- Music related
- Concisely and clearly answerable
- Not a matter for debate
And if that person comes along and chimes in on this meta question, I'll totally consider voting to re-open, but I'll also have to avoid dying of shock because I just can't see how that's possible. And if someone were able to answer this, they wouldn't be too different from me! I use the same software the asker users, I use/have used the same operating systems the asker is asking about, my day job is supporting computers and making sure they are "stable" and querying vendors about compatibility, and I just generally know a lot about both technology and music. And I don't want to touch this question with a 20 meter drum stick. And I did provide a kind of answer and all it was was an argument based on personal experience/my opinion.
Not matter how much we might really want to answer this question, we just can't, and we shouldn't try.
