Which is better Coax or Optical cables


I wanted to get some opinions on which provides better sound, coax or optical cables.  Is there a benefit to using one over the other?  Is there a brand/model you recommend?

what about the previous comment that says "Caution: The optical inputs are not recommended for DSD or for sample rates above 96 kHz. Optical connections may be unreliable at sample rates above 96 kHz. "  Is this true? 

Coax...stop debating it already.  Toslink is inferior.  AES/EBU is another matter.
Optical cables made of glass can be very good cables with high performance but coax cables will be always overall suppirier,they are more transparent, agile and natural. 
many of these replies should be used in a college electronics course on why consumers buy snake oil

if you have an opinion then state why you think one is better than the other

that will make for a suppirier thread
