If anyone is on the fence about buying Sinful vs Ring0 definitely go with Sinful, especially if the aimbot is something you plan to use without being immediately spotted as a cheater.
Sinful is more money up front but you are buying 3 months worth of subs so they know you have money. Sinful's loader is very intuitive as well.
Sinful has smooth aim and it works well. Can definitely fine tune it with time as you learn how to use it.
Ring0 takes a bit of work to get going. Both have no issues with ESP.
Ring0 has some issue where your aim will snap to targets well outside the FOV and it's very obvious when you do an instant 180 snap to a target you aren't aiming at. And apparently been an issue for a while over there. The developer has claimed it is fixed in the latest update but it is not.
I can not speak about the other cheats offered by either of them, this is just for Smite.
