We chose Cunard because my wife loves the many formal nights, and we both really enjoy ballroom dancing in the Queens room.
The service and the professionalism on the Queen Victoria was excellent. I've have never experienced better on the many cruise lines I've been on. Only Celebrity was as good.
Our cabin was sufficient. The only negative things were the poor selection of TV programs and our balcony was much smaller than the one we previously had on this ship.
