NYC-LHR Overnight: UC A350 or UC A330

I have yet to fly the new UC on the A350. I have the choice of flying from NYC to London overnight on the A330 or the A350. For the day flights, I imagine the new A350s to be better, but does anyone have a view on which cabin and seat is better for sleeping?

Thanks

The A350 any day or night! IMHO, the A350 seat is much more comfortable when in bed mode compared to the A333....even more so if you can grab row 1 on the A350.

I second James on this, the A350 every time, day or night. On a night flight the bed is much better, also the change in alignment removes the risk of pax waking you by catching the end of your bed as they pass.

Cheers gents for the question/recommendations - I've just changed my seat to 1A on both outbound/return flights (A350) for end of Feb ….
