What is the 10 most important achivements in order?

[NGM]

In my opinions:

1) Slams count
2) Calendar/Non Calendar Year Grand Slam
3) Total weeks at No1
4) World Tour Finals
5) Olympics Single
6) Masters Series
7) Davis Cup
8 ) ATP 500
9) ATP 250
10) Career matches win

Slams count alone.

Others are not comparable across eras.
