I personally like NCL very much, for us the freestyle dining, choosing where to eat and when is a huge plus. This is also a pretty new ship, the other an older ship...........I personally would go for the NCL cruise. We had two choices leaving New York this winter RCI and NCL in deasd of winter, we were so happy to see the brand new GEM, sister to Jewel leaving from New York and took that cruise. We also like that NCL seems to be more port intensive than other lines for cruises of the same amount of days, however that is very personal and I know others who never even get off the ship. We love on NCL ships the fact the main lobby is higher than many ( carnival) and the lovely deck seven to sit quietly, read and watch the wonderful sunsets and relax before dinner.
