I actually do think it's worth it. To be clear, JC/Hoboken is different than living in Manhattan. If you were asking from the perspective of a Manhattanite, I would say to stay in Manhattan or come here understanding it'd be different.

BUT, in your situation, I think you'll have a great experience. Jersey City and Hoboken are walkable, non-car dependent, and have very neighborhood-y vibes (esp Hoboken), so you'll get that right in your neighborhood. And then, NYC is literally a stop or two away. I'm in NYC most days of the week and can hop over whenever somebody texts to hang out, etc.

Enjoy!
