For me it depends on the cruise length and amount of sea days. If the cruise is shorts 7 or less days Im not in the cabin enough to justify the price difference for the few minutes that I have the drapes open.
I tend to do either inside cabins or Balcony..... the outside cabins just not worth it to just get a small view but no sounds of the waves and no outdoor space.
If I'm on a 14 night transatlantic with lots of sea days, then I will get a balcony cabin. I enjoy breakfast on the balcony and I like to leave the door open a bit at night to hear the waves on the ship.
More important is the cabin location, no bars, clubs or kitchens above or below and no crew entry doors near by.
