A good ping in KS GO should be as low as possible. That's a pretty terse answer, but it's true. CS: GO is a first-person shooter, which makes it very dynamic, and we have to react quickly to the actions of both our allies and our enemies. The lower the ping, the more control we have over the game because we can see the whole game in real-time. We know from experience that a good ping in CS: GO is below 30-40 because a ping with such a low lag is unnoticeable, so the gameplay is very smooth. Note that high ping in csgo can also be higher when you connect to another server far away from you, but current game server technology often reduces this problem but can sometimes increase the delay a bit.
