Well, I just installed Topaz, and I must say that i really do not like the results. Certainly, there is less noise...and the image appears globally shaper, but it is full of strange artifacts, and doesn't seem natural at all.

that's because you didin't used the other sliders. That strange artefact is removed using the Smoothness slider. Also play with the sharpen (remove blur) I forgot how it's called. Anyway I will play with it as soon as i go home. Please redo the test using my suggestions and you'll see topaz is superior.
