They will have a radar suite that’s far more capable, and likely far more expenses, than the set up that will be fitted to the NZ ships.
The RAN ships have also had a lot of hull work competed to restore buoyancy margins, including fully enclosing the quarterdeck.
Yes, ESSM is heavy compared to SeaCeptor, but that's essentially because its a much faster missile with a significantly longer range.
