They should be closed as "primarily opinion based" because they boil down to preference or just looking at comparison charts.
Why you are asking about the advantages or disadvantages is the real question.
- Do you want to move to another product and need that push?
- Do you think you're missing out on something by not trying it the other way?
- Are you really asking about a product recommendation instead? (We have another close reason for that.)
- Do you think something is wrong when you're doing it a certain way? What is the actual side effect you want to really look at?
That some are open is like all questions that don't belong. They were missed at the time. The policy on that is to close them as you come across them. Not necessarily to sit there and close them all when you're trying to prove a point.
