Simplicity is a different animal all together. Personally from a sales side I like the Simplicity, but from a tech side I know most prefer the WICMC. It is decently priced for the product, and from my experience it is pretty solid, especially for an in-skin product. No UM or remote IP administration on Simplicity unless I am mistaken, and it comes in 8, 12, 16, 20 or 24 ports with a min. of 400 hrs storage.
