I just want to make a couple of points in comparison of these two lines as many on board have sailed on both lines.
As a matter of fact just over one month prior I did a 31 day "Around Australia Circumnavigation with New Guinea, Bali, Komodo Island on the Oceania R-Class
1. I am not loyal cruise ship passenger. My priorities are first the itinerary, then the quality of the ship/ line closely behind. Oceania has had my earlier preferred rating. I have sailed on RCL, Holland, Celebrity, Oceania, Norwegian in the past.
A good inside cabin, in fact I love it when there are a large number of at sea days where I can sleep in. I am still not retired and part of the working world. I am able to truly relax and unwind on the ship. I find my self up on the front Horizons Deck 10 forward most of the time.
Went to the Penquin Rescue, our own walking tour, a bit sketchy and dangerous in the downtown, not much here
