I don't like the expanding Snowflake. I have seen that one on recommended outline websites and it's too complicated. I have seen the visual map and it looks like it could have worked in the beginning stages of my stories because I put my antagonist in the middle and everything else revolves around him. I will have to check out the others and see what they consist of. I have not heard of some of them like Pure Summary, Flashlight Outlining, Contextual Preparation. During Nano Prep, I used the Skeletal Outline mostly. Free Writing was just what the stories consisted of whatever was in my head came out on paper.
