Fritz 12 interface vs Rybka Aquarium

Does anyone have any feedback as to which they prefer and why?

Fritz 12 because it has the annoying voice and the ticking clock sound that won't shut off.


All that aside, I actually prefer it to Aquarium on aesthetic grounds.

Certainly both are fine and easy to work with, for the most part. Personally I prefer the fritz interface. Further to that I prefer the previous fritz interface, eg. fritz 9 to the revamped fritz 12.
