I personally stopped playing CS because my friends started using an alt-launcher to avoid cheaters, which added a whole layer of complication that made the game undesirable. Ban waves aren't perfect but in my limited experience, cheaters weren't that rampant, in others experience it became intolerable.
I haven’t played valorant, so I don’t know about them, but what I can say is that definitely other anti-cheats are highly ineffective (VAC being one that is highly ineffective), with blatant cheaters going years without ever being caught.
Hell, blatant cheaters literally stream themselves cheating and their own communities do not recognize the cheating till the stream makes a mistake and selects the wrong scene. This also means that VAC methods of sending footage to random players is ineffective, as some streamers who are very obviously actually cheating do so in front of tens of thousands of people, and those people do not recognize the obvious cheating happening.
We also know game companies don’t care about cheating, as activision admitted in their lawsuit that they leave cheaters on a safe list so long as the cheaters have any semblance of an audience streaming.
It really doesn’t even take that many viewers. Zemie, for example, is a straight up cheater that runs a button activated aimbot and wall hacks. He only averages a couple thousand viewers and is safe listed by a number of game companies.
