HDMI ARC or Optical out ?

Coming out of the back of the TV , I have a choice of "optical audio out" or "HDMI ARC" .
Does one method have any advantages over the other ?
If so , why ?

Thank you and be safe .

I could be mistaken, but I thought there could be some compatibility concerns when using AT&T with Toslink.

In addition to what already has been mentioned; HDMI will transmit the greater bit rate width for some protocols, but optical is more galvanically isolated.
FYI, some of the better glass cables come from:
Lifatec. Wireworld and DH Labs. Perhaps not as critical, there are lots of HDMI cable options, though videophiles seem to like Wireworld
