The best legit cheat?

To be honest their are no legit cheats, by what I mean is you are not playing the game legit you are you are letting a bot do most the work. Unless you mean legit cheats by real cheats that work and are not detected is to find Public cheats that are not patched aka hard to find, private cheats that are not know to the public, paid cheats of course, and last one is your own coded cheats that you made by hand and that is if you know how to code. I hope this information helps a bit.
