All valid points, but I still don't think these relatively minor rationales merit spending 3x or 4x the amount for a ticket. It's not
that big a deal to fly out of JFK vs. EWR, particularly since much of the airports' clientele is Manhattan-centric. As for EUAs, I think we all know they're rare for anyone other than PLTs on the heaviest-traffic business routes, so if your odds of getting stuck in CO coach are 90-95%, why not go with jetBlue and its 4-5 extra inches of legroom and TVs in the seat, particularly if the fare is 1/3 the amount?

Club access can be espcially important when flights are delayed, as they often are on this route. Also, YUPs if elite (if available) and at least the theoretical possibility of EUA.
