I am in similar situation as yours, 27 yo single guy moved here from Bay Area in January. I have visited both DTJC and Hoboken and found Hoboken to have much better vibes then DtJc. Dtjc usually has less going on compared to Hoboken and doesn’t have a cozy feel that Hoboken has. Though you can choose either but stay close to path, commute from path to downtown Manhattan, west village, Greenwich village and even Times Square is under 30 minutes and I have had no issues with it whatsoever. I also decided against Manhattan because city tax is really high and what I get for my money is much better in Hoboken/dtjc then in NYC (not necessarily cheaper though). And if dating and social life is priority then Hoboken should be preferred as it has lot of gym studios, classes and sports league that you can join to meet folks of similar age group. Dtjc also have those but demographics is mostly married couples

Also don’t make a decision until you have checked out neighborhoods as your perception of things could be different to folks here. Initially I was told that Manhattan/Brooklyn should be my first choice but I didn’t like east village, midtown, lic and Brooklyn downtown. Neighborhoods that I liked were Williamsburg, west village and Greenwich village but was priced out of those.

Ues, bushwick were also good but commute was better with NJ path so I ruled those out.
