What is the most updated "system" of MAGIC(K)?

Hello I've been researching occult stuff for a little while now and Thelema seemed to offer a lot at first. Soon after I discovered Chaos Magic and within a few of the books created by Chaos Magic founders is a diagram of how magic has evolved (from Golden Dawn to Crowley to...) and placed the IOT, a chaos magic society, as the "magical heirs". Thus, it seems that Chaos Magic will most likely be replaced (or is already replaced) by a more supreme system. What is the most updated "system" of Magic(k)?
