I see your point of view and do agree that Hans death is very emotional but the immolation scene is ridiculously packed with emotion for me. Ewans delivery on those lines are masterful. And to be clear here, when comparing each of these films as they were theatrically released I would put TFA above RoTS.
P.S.
The music for immolation scene is stronger/more emotional than “Torn Apart” in TFA IMHO
