Hello. You have not shown the sources to which this question refers, which makes it impossible for the question to be answered accurately. However, I will try to help you in the best possible way.
A source that helps you to visualize a moment well, is one that presents a highly descriptive language that presents a large number of adjectives that inform you of many characteristics of that event, thus allowing you to form a mental image of what happened. Therefore, you should look for this type of language in your sources to find out which is the most efficient.
