All things being equal (hypothetical) which do you prefer, XLR or RCA?

Hello All,

Just curious here. All things being equal would you go balanced or unbalanced if you have the option for both? I only ask because I've never really compared-though I have gone both routes at different times. I have gone the balanced route now (power amp to pre, and DAC to pre), but wonder which route you all would choose...Just curious and having some fun...
