Long runs, pro use, quick change, superior protection from interference: balanced is a no brainer
Home, short run,, no interference problem, my experience, no difference in sound.
A Physically Secure connection is very nice, Balanced gives you that if your equipment offers it, one end or both.
Previously I changed everything to locking rca, so I had secure connections.
My only balanced is my Sony CD player. I asked like you are doing.
Several said ’balanced is better’. I asked everyone WHY use balanced? If no interference problem, Why would it be better?
NO ONE answered.
I tried it anyway, no difference in sound.
Balance is a snap in secure connection, and easily released, moved, reconnected. I would use it for that reason.
Rear Clearance: for the connector and to pull it out of the recessed socket, if tight clearance, balanced might not fit.
Right Angle Balanced connectors exist, just for example
