11D or 15C on 33P
 

As above. What are the pros and cons for each of these seats. Thanks in advance.

If on 33P I know immediately one advantage/disadvantage on sitting bulkhead.

More legroom, but no under seat storage on take off and landing. A hard no for me.

The last row especially the window side is more private. You can clearly see what's going on in the entire cabin, and no one will be starting at you from your back. (Nothing creepy it's just people become too tired to watch movies or do anything but can't fall asleep in the weird slanted seat)

I won't worry about legroom unless you are really tall because the seat pitch is great on CX. A quick search shows it's 45in, compare to 36-37 on AA Domestic F

I would prefer last row, 11D have some extra space but no under seat storage also least privacy seat in the cabin IMO.
