There are 4 closing reasons that would apply to questions (excluding the duplicate reason):
Unclear what you're asking
The question is not clear, and it is not possible to understand what is being asked
The question would require to write a too long answer, since it is not being specific enough
The question is asking the opinion of users, or it is subjective
In the case you are describing, a question asking for the best way is subjective: What is the best way for a person could not be the best way for somebody else. Still, every given answer would be equally valid: What is the best way for somebody is equally valid as what is the best way for somebody else.
Questions for which every answer is equally valid aren't considered good, on Stack Exchange. There isn't a definitive answer, and Stack Exchange aims to build knowledge around questions with definitive answers.
With questions asking for the best way there is also an issue with how answers are voted. There isn't a objective criteria to establish which answer is correct, or not. It's not like an answer saying that the translation of sun is luno for which is objectively possible to say if the answer is correct or not. Users, with such questions, tend to up-vote the answer that is closer to their idea of best way, which is quite subjective.
If none of the closing reasons applies, then the question should not be closed.
