Plastic nozzles can break from time to time say if there is a jam in the hopup bad enough and the nozzle slams into it. A metal nozzle will be far less likely to break but then instead of it breaking it might damage your hopup if there is a jam. Also some metal nozzles are known to dent or imprint the BB's when it strikes them which effects their flight path and stability. Also there are differences between aluminum and steel nozzles, not sure what the effects are exactly between those two though.
