A380 for me as 1A/K are secluded and quiet. The A380 I much prefer as a plane and two bathrooms for the cabin and no need to go through galley from right side to get there. Screen is smaller if you watch content but for me I prefer the bed, storage, having an actual blind and the side table (for drinks, etc) makes the sleeping space more restrictive on the 787 for me meaning I have to select which side I sleep depending on the seat.
If you want a giant assed TV and aren’t a side sleeper then 787s fine.
