Generally, I'd say the best method is the one that can work for you, based on your unique circumstances and perspectives. Some people care about pain, others don't. Some people desire a quick end, while others don't mind if a method takes a little longer, as long if it's ultimately successful. I think to find the best method for one's own unique circumstances, one needs to do an honest assessment as to what is important to them, be it peacefulness, quickness, efficacy, etc, and they also need to take into account what "materials" and other resources they have at their disposal. This is NOT to say that someone should just use any idea to try and ctb. Frankly, some ideas can just be simply stupid and can/will result in harming one's self seriously WITHOUT achieving their ultimate goal. No, one always needs to factor "reasonableness" into their idea: What is the likelihood of success with my chosen method? What are the repercussions if my method should fail?
