For years, I flew into Newark, heading for Manhattan. Now, I find LGA to be much cheaper and faster. If I take a taxi, it's cheaper. If I take the subway, there are 2 buses. One M-- bus that connects to the 4/5/6 subways and also to the 1 on the west side. There's a no stop bus, Q--, that connects to the 7 subway in Jackson Heights.
