I am not a fan of either. I agree about the confusion in the names. Right
now I am on enforced pain and using Unity for a week. It isn't so bad, but
I miss KDE. I just like to stay on top and figure that I cannot speak
authoritatively without some direct experience. I do this every so often to
myself --- fool that I am.

Another thing that drives me wild is when I open a deb file and it wants to
use SC and then SC cannot install it and gives you no feedback about why it
won't install. I open the same package that won't install in Gdebi and it
will offer to install, tell me the missing dependencies and
then install them with no problem. I think dumbing things down goes to far
when it does not give you the proper feedback. That is why I stick with
Synaptic. It will tell me if something is broken and allow me to fix
it instead of leaving me in the dark.

Thanks for clearing up the Muon differences.
