One of the great advantages of flying from Dublin is the unique US pre-clearance facility at Dublin Airport — you clear US customs and immigration in Ireland, arriving in New York as a domestic passenger. Combined with direct non-stop routes, it makes Dublin one of the best departure points for transatlantic travel in Europe.

JFK vs Newark (EWR) — Which Airport?

Newark (EWR) is often used by Aer Lingus for some routes and has good transit links via NJ Transit to Penn Station (45 minutes, ~$17). Consider your NYC accommodation location when choosing.
