I grew up in Melbourne and now live in Sydney.
I think there is more in common between the two, than different, obvious exceptions aside.
It is a timeless argument that most people can’t make without being subjective.
Sydney obviously has the beauty - Melbourne does not aspire to be beautiful, but has made itself a destination out of itself in her own right.
I do feel like in terms of domestic tourism, Melbourne has the momentum - booming nightlife, arts, culture, events and sporting scene.
Sydney is lagging in the doldrums a little at the moment - lockout law does not help.
But that is not a “my city is better than yours” simply, one has its cards lined up, the other is working on it, for now.
But Melbourne will never have a beautiful harbour (but port Phillip is beautiful in its own right, especially the eastern shore south of Elwood) and Sydney will never have the sporting culture Melbourne does.
Embrace, love both… They’re both good!
