I think you would get better advice if you gave some context about what it is you are trying to do, or why else you are trying to find out. Adjectives like "best", "simplest" and so on really depend on what it is you are trying to achieve, what your skills are and so on.
The short questions are also not really conducive to getting people to respond, or to upvote you so that you can get more traction.
