We had a Cat. 6 on our first cruise, 3 nites, and a Cat. 10 on a week long. We spent so little time in the cabin that we didn't miss the balcony, but it seemed as though there was a lot more room for clothing storage in the Cat. 6. There was an extra piece of furniture, something like a trunk on end, that we did not have in the 10. And for 2 adults and 2 kids, we need the extra shelf space. Our cruise next month is in a Cat. 8, which will have a window AND the extra storage.

P.S. We were waitlisted on our first cruise for a Category 6, and got it. Maybe you can book a 10 (to make sure you can sail) and wait for a 6 to become available?
