This is just my opinion. I have put a lot of water in my layout and the Magic Water is the very best I have ever used. The Woodland Scenics "realistic water" you have to be very careful or you will get bubbles. I was extremely careful and still got air bubbles that I had to use a sharp point to get out. Magic water is a two-part system and when I mixed, 8 boxes, I never had any trouble with the bubbles and one other thing. With woodland scenic's material if you are going to pour very deep it has to be layered where as the Magic Water you can pour as thick as you want to. This is strictly my opinion. Larry
