In keeping with one being a black box and offering great results and one exposing more controls and generally requiring more expertise ...
Simple Cloud Shader
Advanced Cloud Shader
Because if you have "Easy" ... then anything else must be "Hard", and you don't want to put that in a name! (Even if it is the truth.
)
The problem when comparing the two Shaders for naming purposes is that Matt mentioned there are things the Easy Clouds are currently tuned to do internally that you cannot (yet?) do with the normal Cloud Shaders even with their more exposed and more numerous controls. So, in that case, which one is more "Advanced"? The current Easy clouds give you a faster setup of detailed, realistic clouds at the expense of black boxing a number of the settings and controls to get there. On the other hand the legacy cloud shaders offer you much more fine grained control, but apparently are not able to produce the same results as easy clouds, no matter how much tweaking you do.
In that case, perhaps ...

Just a couple of ideas.
