If the CPW line width (and conductivity, roughness, etc.) is
the same as microstrip/stripline ***AND*** the CPW ground
traces are adequately wide, then the metal losses are
the same (within engineering tolerance anyway).
However, some compromise on the ground strip widths is generally
needed, which will incease the effective inductance and resistance
of the return path, which in turn increases the effective loss
of the line. There are rules of thumb to follow in terms of
how wide the grounds need to be to avoid this, but you won't
hear them from me.
