For Kung Fu, I think the effects are minimal except for small nuances.

horse stance is horse stance. It is either high or low.
bow and arrow are same across all styles, high or low being the thing again.
60/40 step is same same
50/50 is same same
cat stance or empty/false leg stance are same again with the high or low.

punching is either flat fist, vertical fist, upper cut

over hand flat fist is called charp or simply, an overhand in boxing. lol

kicking is flicked, swung off the hip, pivotted, pushed, cut.

There is in my opinion no bad things except those things that are contrary to common sense.

In my mind, most of everything that is out there is rooted in shaolin, even the wudang and other taoist stuff and for the most part the so called "internal martial arts" have all these things as well.
