If you are travelling light or dont mind taking the train then EWR for sure. The flights are cheaper and the airport is generally better than the other two disasters here. If you are driving or taking a car service then LGA or JFK. Traffic is always bad lately as LGA is undergoing huge construction and Van Wyck construction has JFK traffic effed too. Rush hour can be horrid. I flew out of LGA last week at an off hour. Used to take me 4 minutes from my friends house by car took 41 thanks to construction. With all that in mind I would still take that over driving in from Jersey - yuck.
