The comparison of two distinct products with similar purposes, as in this question, seems to be the sort of question that solicits opinion and therefore not constructive. However, these questions are not shopping recommendations as they do not ask for a specific product to be recommended. Should these questions be closed as not constructive?
Yes, these should be closed as primarily opinion based, because they're subjective and there's no real problem to be solved.
A couple of reasons:
It's easy enough to take a look at what both tools offer online and compare them yourself, with regards to whatever criteria may be more important to you (which could be anything). Answers would simply be a list of features. We don't do feature comparisons – if the OP can't do the comparison themselves, then the problem is possibly hidden behind the question and they should probably just ask about their real issue instead.
It encourages subjective answers that are merely of the form "I like X better than Y", simply because. It attracts answers very fast because everyone seems to have an opinion, at least about popular software, and it's a magnet for personal opinion without any references to back it up.
These questions get outdated very fast, since features might change, support for certain operating systems might change, et cetera.
