If we want to draw comparisons between CS and Valorant Tenz is probably the Get_Right of Valorant. GTR played in the best team in the world back then and was the best player, but it was the early days of CS:GO, we did not know what is possible yet. And even still, there are players like cNed that could be better, if they had the right pieces around them.
S1mple on the other hand always played with really disfunctional teams that were really flawed, but still managed to perform like nobody else ever had. Even his current NaVi team still has a mediocre IGL for my money, even though they are Nr.1 in the world.
Having a bad team drags your potential down. People think that you can frag out a lot more, but in a bad team you will have to eco a lot more, will be forced in really disadvantages situations like retakes, and you get less support.
Here a analogy for you: Imagine TenZ and S1mple are NBA players.
While Tenz has players that are good at passing and needs to do his shots from there, s1mple literally has to dribble around 5 players that stand in his way and needs to make his shot.
S1mple probably is the single best FPS player of all time for my money.
