I have seen many similar lectures on security, but My thoughts after watching Red Raccoon's lecture 1. It is the most updated 2. Answers questions and answers well 3. The explanations are readable and visible, so it is fun to watch 4. There are few difficult programs or specific programs, and it works well (Usually there are many, or when you install it, it doesn't work, so you have to find out how to use it) 5. Red Raccoon's unique lab (program) makes it easy to learn (At least from what I've seen from other lectures, the learning hurdle is lower than other lectures, and it's easy to learn by following along) 6. I feel a lot of consideration for beginners, especially since the guidebook contains almost all the necessary content, so it takes less time to look up terms and is easy to understand Conclusion: The educational content itself is detailed and easy to access, so it's easy for beginners to learn I'm not saying that other lectures are wrong, but I'm just picking out the strengths that I felt were unique to Red Raccoon's lectures.
