Somehow I prefer 777 PL than A332. When being in lie-fat mode none of them works for me 'cos of the angel. However 777 PL seats do have a benefit that in Z mode the seat tilt back a little bit so you're at least lying in a 'bucket' with both hips/back supported. On A332 the seat is either flat or tilt forward so making it very difficult to sleep for me.
But I don't get to sleep even in PL. Will be good if BR can re-cabin to real flat seats however I don't think that's going to happen at all. BR makes more money in cargo so passengers are just 'extra' on top of that.
