"Now I just want to know if the new keyboard has more key travel distance back to the like of MacBook Pro 2015." Assuming the keyboards in these new Macbook Pro's are similar to the keyboards in the M1 MacBook Air then they will feel very similar to the 2015 keyboards. Indeed I think I found the M1 MacBook Air keyboard easier and faster to type on vs. my 2015 MacBook Air. The 2015 MBA keyboard definitely is stiffer/heavier. And the keys wobble more - maybe wobble isn't the right word but it's not as precise. Could be it's age at this point and the M1 MBA was brand new; would take more than the 2 weeks I used the M1 MBA to suss out the real differences. I returned the M1 MBA because I needed more RAM; I have a 16" M1 Max on the way. Come November 3rd I'll be able to compare them directly :)
