It depends.  I have witnessed many examples of D-STAR performing well 
on RF paths where FM would have been marginal at beast.  Provided 
multipath is not an issue, D-STAR can outperform FM.  The first 
experiences were on simplex, before we got our first 
repeater.  Simplex was quite active during this period when D-STAR 
radios became widely available, but before any infrastructure came 
along (late 2007 for me).

When the repeater went up, I heard contacts from areas I was _very_ 
familiar with, that I had never been able to get reliable signals 
into repeaters on the same site on bands above 6 metres.  D-STAR was 
rock solid.

Later on, some 120+ mile paths were worked over the ranges, that were 
a tough call on analog.  These contacts were widely mentioned.

D-STAR works, and in the right conditions, it works extrememyl 
well.  However, to be fair, one does have to say that if there is 
significant multipath, D-STAR is the first mode to suffer, then FM is 
the next, and SSB survives multipath even better.
