The Best Bots imo are ones designed with AHK, there's a decent one you can find here
[Release] My AHK OSRS Bot is now free! (Open-Source) - MPGH - MultiPlayer Game Hacking & Cheats
Although he sells the updated version, I bought one off him for $20 AUD, although I'm sure there's other ones around
Simply because there's no automated detection for AHK, where as with Tribot/Sim/Runemate etc, they send/edit packets which makes them alot more susceptible to automated detection imo.
Although, like it says in the above posts, you can get banned using any bot if you use them like a goose. You still have to use them somewhat smartly.
