To determine which would be better for you, larger oceanview or standard balcony...
what will you be mostly doing in your cabin? How many passengers? How much luggage? Having a larger cabin helps if you have more than 2 people in it or more than average amount of luggage, etc. but a balcony is better if you want to enjoy the fresh air, ocean breeze, etc while in the room.
And now that I look closer, 2473 is not set up for more than 2 passengers so the extra room won't help for that purpose. :o
The standard oceanview is what we had last time on Conquest, and they are larger than the oceanview cabins on the older ships...it was plenty of room for DH and I plus our 2 suitcases of "stuff".
I say go for the balcony as the room is plenty big and with a balcony to boot
