Quixel Bridge is awesome, but if you import a material in Blender there are a lot of things to prepare. For example UV map on object, or add more nodes for triplanar mapping. Imagine you have to do this for 20 or more materials in Blender. That takes a lot of time.
Now with the Quixel Helper addon, it is much easier. Just import a material and click a few buttons in the Quixel Helper addon, and you have in no time a bunch of materials set up.
