I think the *best* plan is one that you can feel comfortable with personally and fits your lifestyle. If you pick a plan that you can't live with for the rest of your life, the chances of you sticking with it aren't very good. If you pick a plan that is too complicated or restrictive and you wind up getting frustrated with it, the results will be the same.
There are a lot of different plans out there. They all have in common that carbs, specifically highly processed, high GI carbs, are restricted to one degree or another.
Some people find that they need a highly organized plan to keep them on track. Others like a bit more freedom.
As with most things in life, "one size does not fit all".
