You see this question a lot, and the quick answer is none of them. This isn’t a crash diet. The plan you choose is based on what is best for your lifestyle, none are better than the others for losing weight. You didn’t gain it all in a month, your not going to lose it all in a month either. Answer the questions, choose your plan, be accountable to yourself, track your points, maybe exercise more, and it will work. It won’t be instant, but your weight loss will be as consistent as you are following the principles of the program. Good luck, it’s hard work but everything worthwhile is.
