NOTE: Ultimately Stack Exchange concluded that the particular question you asked about is link spam; after investigating the other questions from the same user, I saw that they rapidly posted the same question (including the bogus Cisco PoE switch hyperlinks) across five different Stack Exchange sites. Those hyperlinks were:
- Technically incorrect (i.e. labeled as a PoE switch, when the model number was not a PoE switch)

- Their website advertised a "Hot sale" for this product (See bottom of this answer)
Editorial note: In spite of our active attempts to get rid of them, the company (r0uter-switch.c0m) continued trying to spam us for three more months after this event.
I contacted the Stack Exchange community moderators, and they agreed that this was content spam. The user was destroyed, and their posts have been removed; however, I responded to your other concerns below...
For sake of argument, let's assume this wasn't a content spammer
The question you're asking about is too subjective and borders on a shopping question: i.e. they gave us two hyperlinks and asked: "which one is best" (with no other explanation of their requirements or any criteria for quantifying "best").
I'm not sure if this is right policy for new site trying to justify its existence and trying to gather user-base
First off, this site is doing quite well given the age of it (roughly six months); our unique visits grow by hundreds of average visits per week. That visitor growth ultimately means we get more questions from people who previously found good answers here. However, we cannot sacrifice site standards merely to justify our existence.
BTW, closure is not final. If the OP wants to rephrase the question as something on-topic (without lying), that's great. If they want to ask this shopping question in chat that's perfectly acceptable as well, although you need 20 points to talk in chat.
If you disagree about the closure of a question, you can always vote to reopen. I would love to see this site vote more for opening and closure, because that is one of the things we need more of. The community owns this site; however, the community should act within the guidelines established by Stack Exchange.
If you seriously disagree about the closure of a question, you've done the right thing. Ask a question on meta. Thank you for asking, but sadly the answer is still the same... it's off-topic as-phrased.
Proof of content spam
For the record, I'm adding a screen capture of the original question (now deleted as content spam), as well as captures from the hyperlinks in the question.
Exhibit A (the original question, now deleted by Oded):
