Of the three, Morgan Street is the most like the "classic" jails you'd see in the movies and on TV. Orient Road and Falkenburg are the new, direct supervision ones, and Falkenburg, IIRC, is the newer of the two, and really utilizes that to the fullest extent. While Orient has individual/double rooms, that you can close the door to and whatnot, Falkenburg is most like a squad bay. They're both good facilities, though I definately wouldn't want to "enjoy" an extended stay there.

And man, those guys on lockdown are complete and utter assholes.
EDIT: Since I can't have fun with my thread title, I just changed the thing to be more accurate.
