Balanced a good decision. Why?

YMMV.  Try them both and decide which one sounds better.  While balanced makes great sense, it doesn't always sound better.  

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

Unless you have a highly revealing system and are spending thousands on cables it won't matter a hoot.

I would suggest get the best quality used cable you can afford, Cardas maybe?

Balanced cancel out RFI from the line You won’t hear it so much as what it does to subtle passages.

I have to agree. I have done extensive comparisons and even with long runs… 5 meters I really could not discern a difference. Theoretically they perform much better… but I think in reality it is a function of the components you are using.
