Simply put, Magisk doesn’t modify the system partition hence allowing for a more cleaner install which can be removed easily if need be.

Also, unique to Magisk, are the Magisk Modules which you can install and operate using Magisk Manager app. These modules add in functionality to your smartphone and also allow you to modify certain functions to your needs. As said previously, you wont be able to run these modules on any other root utility.
