To me it depends on how much room there is and the situation. Just a few cars, there's no real gain in filtering and it's safer to just queue up. If it's ridiculous though and there was room for all those cars to pass me rushing up to the intersection as they tend to do, there's probably also room for me to pass them back. Except for right hooks. So I don't like to be directly right of the first car unless it's a left-turn only lane - establish a position while stopped between or in front. Also if it's really narrow on the cross street I'd be reluctant to share the lane on the turn (otherwise I would share while turning and no one is being slowed down much), but if you have to take the lane in the turn is the road so narrow that you have to keep controlling the lane afterwards and they all have to wait again? I don't think I would jump the line in that situation.
