Personally, I like both lines. My favorite ship was the Harmony of the Seas and the entertainment was top notch. However, I like NCL's varied itineraries, the wonderful spa, and that NCL seems to renovate their cabins more often. While the Harmony was my favorite ship, the Pride of America itinerary was our favorite. Looking forward to sailing the Jade this Fall out of Greece. Next booked cruise after that will be the Celebrity Apex. Variety is the spice of life at least for me.
