I like the positive lock of XLR connectors
I never heard a quality difference, and I never had an interference issue, or long runs: however I did get more quantity, i.e. slightly stronger signal out of XLR opposed to same unit’s RCA outs (not always).
You might get both the locking feature and stronger signal advantage using an adapter to use XLR out of a unit to go to a unit without XLR in, they come in all kinds. Of course cables with xlr/rca/variations exist, adapters let you use an existing cable.
