You may need to give us a little more information to help. Equinox is a brand new ship and Ruby is pretty new. Both a relatively similar in size.
Are you looking at cruising the Mediterranean or Caribbean? We have looked at both ourselves for a Greek Isles cruise next summer and are leaning towards Ruby Princess but think we would be happy with either.
Congratulations and have a great honeymoon.

I have sailed Celebrity Infinity and Star Princess. I like Princess way better. Nothing to do on Celebrity and on my cruise the food was bad. Plus the Rudy Princess has Sabatini's on board. This is an interesting article about Rudy Princess and Celebrity Solstice. Princess & Celebrity add state-of-the-art vessels in Caribbean
