Not just time saving, but since I use it I did not have to re-tie my laces during the day, it looks very symmetrical, and I regularly have the silly but satisfying experience of people seeing me tie my shoes and say "how did you do that?". This is the knot I am teaching my kids (my wife can take care of the "standard" one).

My kids only know this way of tying it, I was surprised how easy they learnt it vs what other parents refer to me for more traditional ways
