I should know, because I decided years ago to take the path of "if you can't beat 'em..."
Once I did, it became painfully obvious how many people cheat. With x-ray, "wallhacks," or 3D "radar," with bounding boxes around all players, it became readily apparent who's aiming at and/or chasing players who shouldn't be visible, always choosing the route the opposing team is taking, without fail. And who on the other team always takes the route you take, chasing you through any maze with no problem, even turning around when (and only when) you try to flank them. Also anyone who out-scores you while cheating (particularly if you're "rampaging") is definitely cheating as well, because you're already doing better than is humanly possible. And believe me, you'll get out-scored plenty.
I would be glad to have functional anti-cheats, but it's just not possible in my experience. Cheats are available on day one of any game launch, or day 2 at worst. It's big business (clearly). Even kernel drivers like this have patched kernels to get around them.
For now, cheating makes games fun to play again. Aimbots aren't perfect anyway, and even if they were, nobody can look or shoot everywhere at once. You still have to manage ammo, you still have to reload, and you can still get the drop on people (cheaters) when their attention is focused elsewhere, and you still get killed while cheating. Sure, it sucks for the people who don't have cheats, but I'm not going to be one of those people as long as a large percent of other people are cheating too. Unless and until anti-cheating actually works, it's just evening the playing field as far as I'm concerned.
