It is generally believed that drawing by hand can be more beneficial for comprehension because it requires the brain to engage in a different way than when using a computer. When drawing by hand, the brain must process visual and spatial information and translate it into physical movements, which can help with understanding and retention of information. Additionally, the act of drawing by hand can help to facilitate creativity and problem-solving skills.

That being said, both methods of drawing can be useful for comprehension, and the best choice will depend on the individual and the specific situation. Some people may find it easier to understand and retain information when using a computer, while others may prefer to draw by hand. Ultimately, the most important factor is to find a method that works best for you and allows you to effectively process and understand the information you are trying to learn.
