Riot definitely has one of the best anti-cheats, but there are still many providers that are reliable and undetected. It all comes down to your budget and skill. If you want a cheat with esp and aimbot that's not DTC, you probably have to get invited to a private one, and it is not cheap either. If you're decent at the game playing legit, you can go for a color aimbot that is much cheaper and safe, but it doesn't have esp, and you need actual game sense. From my experience, I have bought countless esp cheats but always got banned. Im currently using color aimbot that is private and I haven't been banned for over six months on all my accs. But you can still get a manual ban if you are not smart and don't have any game sense. My accounts are all immortal or diamond btw and I would say I'm around gold or plat in skill but cheating in high elo for so long I have really good game sense
