IMO, it is, but if it isn't, I'll vote to re-open.
(Please don't downvote it; I'm just trying to get the right thing done regardless of whether I'm right or wrong.)
Too broad: it asks for a comprehensive comparison of two platforms, and general information on one of them. That's simply too much for the scope of one question.
Note that the list aspect of the question falls under this reason, not the custom off-topic list reason, because the question asks "what is the complete list of differences between X and Y", and not "I have X, give me a list of products which do basically the same thing so I can pick one".
Primarily opinion based: it asks for pros and cons, but those vary depending on the environment, business needs, and usage. Whether product X has feature Y found in product Z is a factual question, but whether having Y is a pro or con is not.
The subtext of the question is "my business is considering a move to this platform, and I want to know if it's a good idea". This isn't answerable by detached experts with facts. It can only be answered by OP's business by weighing relative costs and trade-offs. To be fair, the question does not ask "is it a good idea" - the OP will be making that decision - but SO doesn't know what's good or bad for the company, so responses addressing these will be opinions unsupported by facts.
The question "I'm thinking about switching my C# app to Java instead, in what ways is Java different, and would those differences be better or worse?" is off topic in essentially the same fashion. The first part of the question is too broad, and the second part opinion based. Hopefully the analogy helps clarify things.
This answer intended as explanation for the OP of the question in question.
