There must be a really good reason for you to settle in NJ $$
It really all depends where in NJ you are talking about. There is just no good way to get to BWI that you won’t run into traffic. I95 is miserable as is any of the turnpikes. There are just so many people that you’re guaranteed a slowdown somewhere in the trip. Early Sunday mornings are usually the exception. Even the middle of the night is a pain because that is when they decide to close a lane or two for construction.
In a previous life I had a lot of experience driving to and from NJ airports from PA. Almost every trip was on 95 or the turnpike. I would not wish that on my worse enemies.
