I don't think it's a better way. How I understand it, the idea is to train your mind not to wander and instead focus on the senses. Then you'll more likely focus in your dreams and hopefully be more aware of your state overall. In SSILD you focus on senses and after a complete routine you fall asleep quickly. In WILD however, it's maybe good to focus on those wandering thoughts.
