Not what I hoped for...
I do not have the SiliSponge to compare to however, this seems to be a fairly useless product.  It didn't really help me use less product as I needed to keep going back over areas to ensure coverage.  The foundation applied poorly with lots of streaks.  This product didn't blend, only spread product on my face.  I still needed to use my BeautyBlender to blend the foundation and have it look natural.
