Our previous trip was on Princess line (Emerald Princess), which was superior in EVERY aspect.
We had a balcony upgrade from BD to BB deck 10.
If this was an upgrade..would hate to see BB. The balcony chairs were covered in paint spots, as was the door, with an oversize table, and a door that opened into the balcony,..it was an effort to get out there. (a folding hinged half-table would have been much better.)
