Google maps is pretty accurate for public transportation and timing (set your arrive by time to roughly your work start time to get correct schedules). In general in Jersey City, the closer to the PATH station, the faster your commute, but also the more expensive your rent. PATH from Jersey City to 23rd and 6th is likely about 20 mins so it will depend on walking time to and from PATH station about your commute (and/or if Chelsea location is far enough you want to transfer to subway or bus in NYC).
