It's really up to you. Personally I would get the bike I liked the best if I had the money (granted they all fit). However, the dilemma seems locking it up in NYC.

When I took a night class at Fordham University (Rose Hill Campus) there was a security booth at the gated entrance. The only problem would be sometimes there wasn't a security guard (could have been doing rounds or something).

Also, video surveillance needs to work (sometimes they have dummy cameras or are have them pointed in general areas), needs to be clear (to recognize an individual), and needs to be monitored (so someone can respond if something is happening).

Basically before deciding what to purchase, just double check the locations you plan on parking it. If money is an issue then you may want a beater bike for commuting and look at the less expensive bikes you listed above for other purposes.
