My chosen style is between 2-3, more close to 2. I actually like number 1 as player sometimes, if I totally agree with a story. I don't dm that way ever, too boring for me. I've never ever had good experience of 4th choice. Too much freedom, is pretty much too near to nothing to do. DM should provide something more special that other stuff. Not something between "you figure it out", "llong list of quests, of which none read as very important stuff".
Maybe there are dm's good with style 4, but it requires lot of prep and ability to make it sound inviting. Most players I know exect dm to tell most of story, as do I. Mainly because I like stories that have mysteries and things I can figure out. If I am creating story it's not suprising enough to me, it is just reactive cconsequences. Even rolling dice doesn't save it.
You can rebel against railroading, but can do next to nothing to too much freedom. And I have often noticed that if dm:s don't like idea you want to do, they put their effort to killing that story. Well, my real life experience, there are many out there I believe that work it better.
Anyway, I think game should always have some kinda theme. If there isn't one, then I wont' play. I mean themes like "war against something", "aliens invading your home world", "you are all immortal, and don't know why", " etc and even combine some.
Not only that makes campaing immediatly sound more interesting it also makes it easier to create characters, and there easily is certain party combabilitly. And you are not so easily confused if you need social character or just lot of combat related skills or whatever else or inbetween.
