I use a water brush when I'm on the move. I like that it consolidates everything and there are no spills. I use a real brush, with a container of water, and a paper towel, when I'm at home. The major difference between the two, in my opinion, is water control.
With a real brush you can be more precise about your pigment/water ratio. You have more control over how much paint is on your brush. With the water brushes, I find I either have too much water on the brush or not enough. It's hard to control the flow. (Which is "deep", if you know what I mean.) The inability to be very precise with the amount of water on the brush means you don't have as much control over the paint mixing on the paper.
Like I said, I use the water brushes when I'm on the move. I sacrifice accuracy for speed and convenience.
There may also be some issues with the material the brushes are made out of, but I'm not professional enough to know.
