For me the top 3 are : 1) Accuracy 2) Distance 3) How it looks.
Accuracy is all important cos if you are in position on the fairway , you are in play and can maximise your chances on the hole.
Distance I now need more of as I get older.
The look of the driver instills confidence and that helps me to consistently drive well.
Must admit that compared to a couple of years ago my driving is only so so.
