When I was there in the summer I tested both RBF and non-RBF txs, and found that instant confirmation was inconsistent for both. Often a non-RBF tx required a confirmation, often a RBF tx would give me cash immediately. There were no guarantees either way and the RBF flag didn't seem to make a clear difference.
