Think of it this way - your brain can pick a voice out of static better than 
a computer can pull a digital signal out of the same amount of static.  So, 
you have to have more signal to make the digital system work.  When it works, 
it works great, but low signal and multipath (like ghosts on TV) that your 
brain can deal wit would kill the digital signal.

When it works, it's going to be clear, but once massive error correction 
kicks in on a bad signal, it is going to go bad fast, not gradually like an 
analog signal.
  
I also don't like the digital audio over 2-way.  It sounds "mushy" or 
"muffled."  There is also a noticible lag between when the sound happens in 
the transmitter's microphone and the time the same sound comes out the 
receiver's speaker.  Something like a quarter second or a bit more.
