Looking at flying 1st MAN-DXB-BNE-DXB-NCL (last flight J as no 1st)

We are thinking of having a couple of days in DXB on way out.

Does anyone have any opinion on which flight from DXB-BNE is best - the early morning departure (02:50) Or the later one (10:25)?

Both are A380 any suggestions or opinions would be great - thank you in anticipation
