Looking at two flights.

16:00 3 Nov
21:30 3 Nov
City Airport (London)
John F Kennedy (New York)
BA0003
British Airways
Club World

17:15 3 Nov
21:15 3 Nov
Heathrow (London)
Newark (New York)
BA0187
British Airways
Club World

Considering they both arrive around the same time (although the LCY one takes longer), which would be a better option?
Never flown CW so missing out on a chance of the lounge at LHR would be a downside and was considering flying into LHR from Man rather than by train so that's another plus for LHR.
The LHR flight is listed as a Boeing 777 which is not the most popular plane with a lot of people here compared to a 747.
