Xor or single ended?

Hi Goners!

I am sure this has been gone over but i seemed to have missed finding it...
What is preferred...A single ended tonearm cable to an orca phono input or a xor balanced termination tonearm to a balanced xor phono input?

Please, if you answer i would appreciate having solid reasoning as opposed to one"s own preferences...

I very much thank all for helping me understand.
