Well, I would pick 7442 b/c it is an aft facing balcony. Those balconies are a lot longer. I have never personally had one of those balconies, but people on this board really love those balconies!!
In addition, the other room could have hall/elevator noise due to its location. Just my $0.02. Good luck and have fun!

We sailed on the Glory in 07. We had 6454 which is the one directly below 7442. We loved it . The balcony is much deeper than the side balconies.
Also with that location you can see around the dividers on the Port side very well. In the evenings you are protected from the breeze, and can sit out late if you want.
On the down side we could hear the Kareoke at night. You would be one deck higher so it would not be an issue. There was some soot on our balcony in the morning which was cleaned up daily. We also felt more vibration IMHO.
Bottom line is we would take an aft balcony in a heart beat.
