I've always been a big fan of stealth games so I like to do things stealthily, I can never bring myself to try any other playstyle. I stalk the enemy from the shadows, strike when the moment is right, then vanish back into the shadows as if I was never there to begin with (aside from, uh... all of the bodies that were left behind).
I think the only times I don't use stealth in the fallout games is if I just happen to get ambushed out in the open while travelling, in those situations you have absolutely no choice but to fight and defend yourself.
