This is really dependent on the airline you fly. There are many people on BA who swear by the last row in UD business class. This is because the window seats face backwards, which allows easy access and on the side opposite the stairs, great privacy.

So which upper deck seat is best for space for a window seat?

Again, this is really dependent on the airline and how it configures the seats. Which airline are you planning to fly?
