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

Thanks for the responses! @testpilot and @ron_hartman these are EXACTLY the kind of responses I was hoping for - thanks Folks!

More great responses! I do love the locking grip that XLR offers. What I have noticed though is that some manufacturers charge the same for XLR or RCA. While others charge almost significantly more for XLR (Transparent Cable-not a knock I do love their cables).

This is awesome, thank you all you've certainly ticked the box for "having some fun" on this one :)!

Appreciate all the great responses, thank you All! Sounds like XLR is for the most part what most prefer. Like I said I have gone balanced now and will not go back I was just more curious than anything else to see what most here prefer. But I definitely appreciate those of you that have done comparisons and shared your findings in your own systems, so thanks for sharing!

@jjss49 good point about the loudness perception. I actually fell for this way back in the day comparing Definitive Technology speakers vs PSB's. The Definitive's being bipolar (and more efficient at the time) seemed to completely overwhelm the PSB's. However I soon realized after I brought the Definitive's home that they weren't quite as detailed and did not have that razor sharp image that I was looking for for music, whereas as it turned out the PSB's did. The DT's were great for HT but not as great for being able to close your eyes and actually see the band playing in front of you while spinning a cd...I didn't keep the DT's for very long and never looked back...
