Seats in all rows have the tray table in the armrest. Only difference I noted was that row 1 has no underseat storage in front. I'm not sure if there is more leg room in row 1, as you can only stretch your legs up to the bulkhead - in other rows you can stretch your legs under the seat in front of you.
Personally I prefer the center pair as both seats can access their own aisle, so no one has to climb over you to get out.
