I think different people have different ways of learning, and therefore, may find methods that work for them that are different for others. As a teacher (for 40 years), I know that people have different learning styles and I personally find a certain method better than the method that works best for my husband! Perhaps briefly trying out 2 or 3 options will determine a method that ‘rings true’ for each person. And in the meantime, you may learn a few things regardless of the method you end up with!! Good luck!!!
