I am referring to this post because there is a lot of confusion:
So it was closed as off-topic because it was deemed subjective. I believe the OP did change his question so that it would not be as subjective by asking "What are the differences between A and B?" This can be answered very specifically.
In the comments someone referred to this Meta post stating that it should be valid to ask these sorts of questions.
I also found this question that, while not having an accepted answer, the only answer given stated it should be valid as well.
So clarification as to why this question has been closed as off-topic? If it's simply the question title, why not just edit that rather than close it?
