Creams were much easier for me to get working at first (Proraso and KMF) as I was making my lather in a bowl when I started, but lately I go to soaps more and more as the experience is much more enjoyable (I am strictly a face latherer now).
I like loading my brush and working the soap all over my beard till I have good coverage of a really thick coating before slowly adding water and watching the volume build.
With creams, they foam way too quick, so I don't get to really work them around as much as I like. Although maybe I just have too much water in my brush.
I go to creams if I am in a hurry, but the rest of the time I love the experience of my soaps.
