I agree, "Grandeur" is the key word for QM2, however I think Queen Victoria is a very beautiful ship inside with a lot of features unique to Cunard - plenty of shipboard memorabilia, a beautiful two-story all wood library with a circular staircase. There is a lovely theater with box seats.
The only drawback I saw was that the storage space is somewhat limited in the staterooms. However, if you like Cunard and see an itinerary on Queen Victoria you like I would not hesitate to book it. It is a beautiful and efficient ship.
