Need help choosing where to move?

So I'm 27F, no kids no pets. I already have two areas in mind - Jersey City and Brooklyn. I've visited both areas multiple times, but I cannot decide which one to choose! So that's why I'm asking if there's anything else I should consider, besides the bottom list:

Jersey City:

- Beautiful area - has a promenade, tiny beach, cleaner, not a lot of crowds

- Also has a light rail train that goes to other parts of NJ, plus a train that goes straight into Manhattan. However, it seems like that train is not reliable and sometimes shuts down on the weekends. I don't own a car.

- Apartments are MUCH bigger for a cheaper price. This helps because I work from home.

- But there's absolutely nothing to do in the area besides eat and drink. I'd have to rely on Manhattan for entertainment but as I said before, the train there isn't reliable. Plus Manhattan is expensive. As a result, I'm scared I'll feel very lonely here.

- Not very diverse. Jersey City overall is known to be very diverse, but not the downtown area (where I plan on living)

Brooklyn:

- The apartment I found is in a beautiful, serene area. 

- But, the apartment is much smaller (480 sq ft), though it has a ton of amenities + coworking space

- EVERY thing is within walking distance (grocery, entertainment, gym, etc)

- And almost every single train line is nearby as well

- About $300 from my monthly salary would go towards the NYC local tax, which really sucks

- Much more diverse, which I like

- Brooklyn is more dirtier
