I personally like both, if it's good it's good. I use soaps most of the time, because in the house I have the space and don't mind loading the brush. However...

The utilitarian value of a cream is superior to the soaps in one respect: transportability. The dopp kit can be easier without a brush and puck of soap. For this, of course, I don't bother with an open razor, either. I like the creams because I can put as much as I want into an empty lip balm (kifflam!) container and apply with fingertips.
