"Best" in what way? For speed? For move efficiency? There are now more last layer subsets than this now. How can you possibly persuade us in a seven minute video that your specific chosen combination of subsets is the best?
Unless the video consists of an ingenious proof style which manages to cover all possibilities and probabilities, I am probably going to make the educated guess that this is just your (current) opinion based off of your exposure to the cube so far. Nothing wrong with that.
