Bronze is supposed to be more resistant to fatigue than brass. That would make it last longer. This is very difficult to demonstrate requiring many harmonicas, lots of time to play them to failure on a machine, and careful data analysis.

No. The properties that affect vibration, elasticity and density, are very much alike. The sound comes from the changes of flow area as the reed swings through the slot. There won't be any perceptible difference audible between reeds designed to have the same stiffness and pitch.

Yes.
