I just completed the Level 5 TEFL course. I will compare it to the Level 3 course I also took with i-to-i and say that the Level 5 does require more homework, but that's where the added value is. There was a bit more variety of learning types with the Level 5 in that each section had a short introduction video and there were several videos to show how teaching with the methods actually looks in real life. I would like to see some more interaction, even if only with an AI. I do see how an in-person course would be better for me in general, but they also cost substantially more. Overall, it was a good value for the price. If I had it to do over again I would still have chosen the level 5 over the level 3 only because the homework assignments really showed me the amount of thought and work that must go into each lesson.
