The rooms are the same size it is a personal preference if you want a balcony or not
We have done both cabin types & we did not use the balcony much
Your cruise is port intensive .. you need to ask yourself how much time will you spend on the balcony?
We did 32 days in C1 cabin deck 4 & 26 days in B2 deck 6
We found we spent more time on deck or on shore than in the cabin.
enjoy the cruise
