For brushless cream, I used Kiss My Face shaving cream for a long time, and it works pretty well. Be sure to use a lot of water, so you won't really get a lather on your face, but more like a thin layer of soap. The extra water makes things slicker, though.
I've also used Proraso (or C.O. Bigelow) cream without a brush, same method, lots of water to make things slick.
