I use shaving soap and a brush/mug when I'm home.  This is a high quality, inexpensive system, but it doesn't travel well.  On the road, I generally use a can of gel, which is more expensive, messier, and slower than a brush and soap.  This stuff is more expensive than gel, doesn't lubricate as well, and is more difficult to apply because it doesn't "stick" as easily to wet skin.  I give it two stars because I'm going to use the rest of the can, but I sure won't be buying any more.
