Most (all?) of the A330s have the regional J (the A333s have the longhaul J and they are all committed so I doubt ever used for DPS). Almost certainly you will get regional J (which is perfectly fine for such a short flight, quite comfy as a seat, just not comfortable for sleeping). Obviously the 744 is nicer, particularly if the flight is sold as 2-class and the F section becomes the Diamond seating area.
