whilst the later JFK flight may be attractive in terms of it is 1hr 15 mins later then the EWR departure it also takes 45 mins longer to get there so eating into that 1hr 15 mins.

OP also says the EWR flight has longer transits later on so the time of arrival at the ultimate destination also needs to be co spidered.

if the later JFK flight (despite the additional time and risks of getting there) results in getting to the destination much quicker then that might prove the better option.

OP needs to consider the trip in toto not just one part of it.
