Either a square knot or a “granny” knot will work. A lot of people don’t know the difference, but it’s actually a pretty important distinction in different types of rigging because a square knot is so much stronger and more secure.
Granny knot will come untied easily so it only kind of works. Most people who use granny style probably double it up because they get sick of re-tying their shoes all day.
It’s the same knot (square knot) unless you’re comparing it to someone who’s ties their shoes wrong.
Edit: also, the quick-tie knot OP is talking about is called Ian Knot or Ian’s Knot. It’s a square knot but tied faster.
