It really isn't a fair comparison, the Murano is a much higher end vehicle, it is larger and a lot more expensive. The Rogue will beat the Murano in fuel efficiency by a wide margin, and the smaller size of the Rogue is a bonus to those who drive in heavy traffic as it will be more manueouverable and easy to park. But beyond that, the Murano is more powerful, more refined, quieter with significantly more sound deadening measures.
That being said I've always felt that the Murano is one of the more over-priced vehicles on the Canadian market, especially considering it does not offer a 3rd row seat option like major competitors do. But, if you want a more luxurious vehicle and the price is right, go for it, the Murano is definately a very nice ride and I especially like the styling after the refresh in 2010 I believe it was. You may want to check out the Murano forum to get a more opinions, most Rogue owners will be of little help with a Murano purchase decison!
