Aesthetics is personal preference. The only person who knows if it's worth it or if it's a "good" reason is the owner.
SQ-wise, it makes no difference. So it's pure preference.
Would I do it? Yes I would. I like to see the all-XLR team on the back of my Yamaha pre-pro. I don't want to see any RCA cables on the back of my Yamaha (or anything else
). It's just personal preference.
Heck, if they ever make a XLR-HDMI cable, I would buy them.
