Flown all 3.
332 comes in 3rd.
Prefer 787-8 and -9. Would like a little more space, but no rocking issues (yet). When flying on the -8 with MrsDallas49er, we prefer window and aisle, and 2, 3, 4 D & H on the -9. Traveling separately, I'm 1A or L if possible. She is a more center window if possible.
Hope this helps.
