Melbourne is well known for the world's most liveable city in the world. Holding that title for 5 years running the inner riverfront hub rounds has definitely contributed to that. If you're after the culinary adventure and fantastic ethnic cuisine then inner Sydney is the place where you want to be.
Melbourne is also known for its festivities with the Spanish festival taking place at the Fitzroy Gardens and the Italian festival taking place on Lygon Street. Sydney is also known for variety of exhibitions which take place at Sydney Theatre Company, Hamer Hall, Australian Centre for Contemporary Art, Arts Centre Sydney and the Sydney Exhibition Centre.
