I use North up when the distance to travel is more than a few miles but I use direction up as I approach the destination. I find it easier to navigate local streets in direction up but highways in North up.

I voted heading up. Mostly because I tend to keep track of which direction i'm heading in subconsciously. Or at least, can determine it fairly quickly.
However trying to take the time to look at a panning map and determine what's in 'front' of me is somehow mind-boggling.. Though I can do it easily while sitting still.
