In a comment that might be from another era, assuming that the words "a situation that requires any kind of report" mean what they say, you will, I hope, be guided by your professional integrity, if you are an aviation professional holding a professional licence.
That guidance will tell you that you have, in fact, no choice.
Use of a confidential reporting scheme is fine, of course, and in any event you should never, ever, be penalised for reporting something that requires a report, except in the unlikely event that you are reporting a deliberate error on your part.
