Track up is my preference.
In a past life I flew one with heading up and one with track up.
I prefer the track up - you just plonk the track line over the waypoint you want to go to and you go there - the drift sorts itself out.
Similarly doing approaches particularly raw data ones in the trembling cave, if the CDI is centred, and you are tracking the inbound course you must be doing OK. Again the drift sorts itself out.
Twin locs and single engine raw data ILS's are much easier with this method.
