I was just in the 333 which I assume has the same BE config as the 332 (but no mini-BE behind 2L). We boarded 2L, all BE turns left.

This seat is now my favourite lie-flat in the DL fleet. The angling is good, towards the window for the window seats, and towards each other for the middle section -good for traveling together. I was in one of the middle seats, traveling alone. It felt private, though I would have selected a window had one been available.

The space and pockets are generous, the seat and foot rest are comfortable (they seem a bit softer than the 777 and the 763/4), the AVOD screen is large.
The seats felt less coffin-like than either the 777 or the 763/4.
