Very different games so it makes comparing them difficult and often unreasonable. Counterstrike is more skill based due to the general layouts of the map being static and consistent for the players, while Rainbow 6 Seige is more on gameplay strategies with scouting sites, making kill-holes, and using gadgets to gain an advantage over an opponent. Plus tickrate is better in cs:go and higher ping does not give an advantage, unlike in rainbow six :shrug:
