I prefer the rocks.

With pastes, one of two things is happening, and I'm still experimenting. Either I'm not using the pastes correctly, and as a result my edges are not great....or....I'm using the pastes correctly, and I don't like the feel of them. Regardless, I'm still experimenting and in the meantime I finish most of my razors on the stones, because I DO like the feel of them when I'm complete.
