Bayonne and Communipaw aren't path stops, you take the light rail to the path. Which might be fine for your needs, but something to keep in mind you do have to transfer if you plan to head into the city.

And there is nothing wrong with JSQ, but it is urban gentrifying area where you will see homeless people hanging around and the like. Same with Communipaw. However both neighborhoods offer more urban amenities within themselves than Harrison does.
