MeshCAM is not quite that simple, but close.
Personally, I think they are both about the same, as far as complexity goes. Neither is too difficult.
In Aspire, you just import the model, draw a rectangle around it, and generate the toolpath.
In either one, you still have to enter your stock size, choose tools, and set toolpath parameters.
Is either one, you may need to move the model to the correct position in your stock, depending on how the model was created, and it's coordinates.
