Hi Guys,
Sorry Princess did not work for you. But, that's why there are so many cruise lines to choose from and each of them have their "niche."
We have cruised both of these lines many, many times and some of the things you mentioned I never picked up on. Selecting the right cruise line is a very subjective thing. You know what is important to you and you can be the only judge of what is "right" for you.
I found more difference between ships of the same line than between the lines themselves. Our recent Dawn Princess was a real mixed bag. Perhaps the worst Princess cruise we have ever taken, but our Room Stewardess was one of the best we have ever had and the Production Shows were the best we have ever seen aboard ship, but, our waiter and asst. waiter while very good at their jobs had zero personality, and the party hosted by the Captian for the 20 most traveled couples aboard was the worst I've ever attended, so go figure.
A couple of little touches you did not mention for Celebrity is being greeted at the gangway and escourted to your room and "real plates" at the buffet not plastic junk. A minus for us on Celebrity is the lack of laundry rooms, especially on long cruises, makes packing a lot more difficult.
So all this being said, I'm glad you got to make your own comparison and arrive at a decision which is right for you. I'm exploring Oceana and Altimara now for future cruises. I think you would enjoy Silver Seas, but their pricing is kind of out of sight these days.
Welcome home!
