^His software is really good but it cuts your in-game FPS to half. If you have a trash computer like I do, avoid. Other than that, just go with Yazzn. It has some cool features too.
If you think your computer won't be able to handle Yazzn, I recommend getting StealthMode with the aim assist version which does not include ESP.
You're going to get banned sooner or later with an ESP anyway. So, to be as legit as possible aim assist only should be the way to go.
Also, you should avoid buying any software other than those listed as legit in the Legit/Scam cheat providers list.
