So....
What was the question?
I dont really think there is a difference except which leg you kick with the front or back foot from the fighting stance.
I if you kick with the back leg, you do a "pop". But if you want to kick with the front leg you must do a step in, and then it becomes natural for it to be the "jump" version. Jump version is a bigger movement -more powerful, but way slower -and you must start from a longer distance. Usually not practical unless you can disguise the lifting knee as a kick
You cannot really do a pop version with the front leg or a jump version with the back leg.
