It really depends on the level of cheats. Someone using wall hacks has a huge advantage, depending on the game, but it doesn't take that much more skill to outplay them. But when you get to a point where the cheats aren't just a tool anymore but do most of the work, the skills required to still win get so astronomically high that you will lose every time unless you are a top 0.1% player. Which isn't really fun anymore. And many cheats nowadays are exactly that: practically unbeatable. Not a challenge, not hard but doable with enough work, just unbeatable
