Newark Terminal C is nice. Terminals A and B are still stuck with a layout that was designed right before security checkpoints really became a thing, and consequently doesn't accommodate them well. Not coincidentally Terminal C is the exclusive domain of a single airline (United), who could finance the improvements and realize the benefits of a renovated terminal. Terminals A and B are shared between a bunch of airlines, so no individual airline has much of an incentive to finance renovations. IMO Newark's integration with the train system is much worse than JFK's, because the Newark AirTrain is slow and unreliable, and there are often 40+ minute gaps between NJ Transit trains at the Newark Airport stop. The JFK AirTrain is speedier and more reliable, and the combined frequency of LIRR and the subway is much higher at Jamaica.
