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?

I have always preferred coax over optical. If you have to use optical get a good glass cable, not a plastic one. To recommend coax we need a price point and what equipment you are using
