I'd like to humbly recommend
Synthetic Skill.
We are external and offer greatly optimized performance for minimal impact, streamsafe, as well as controller support. While we are new to the COD scene we are not new to the cheat scene, you can see our stickied thread in the Dark and Darker section of the site. Inside that thread you can see pages on pages of positive reviews, as well as seeing how well our external products perform. (400+FPS overlay in DND while rendering pretty much everything)
While I would not compare our product to any of those mentioned, I would state that our product is very safe. Our product is population controlled with a user limit, while it is not private, it will never grow over the set limit and end up with thousands of users. At this time there are less than 10 users on our MW3+Warzone product.
I'm not going to spam this post on every single COD thread, in fact this will likely be my only post in this area. Feel free to check us out if you are curious.
