If you are tall you should go for the exit rows no matter which seat. If not that then an aisle seat without box (middle section). The 332 is missing the second set of exit seats but they have those mystery exit seats in row 11, hidden secret. Why did Airbus put the boxes under both window seats? If I remember correctly Boeing does half and half so the mirror image of the seat does not have a box, that is where the seating is symmetrical. Other than that I really like the 333 and 332.
If not for preselection of exit rows I would be gone from NW. Only thing keeping me is they changed the rules on Coach Choice.
