Best double window alignment seat?

Doing my seat selection at 330D and everything is available, the route (NRT) is guaranteed A350 but not necessarily NEXT. Left side is preferred.

2A: Perfect for non-next, not aligned on the next - too forward and the 2nd window overlapped by screen?
4A: Pefect for next, non next aligned poorly.
6A: Quite good for both.

So is the safe play to always get 6A, unless the frame is absolutely confirmed, which is never?
