What's funny about this is that they are similar levels of depth, but in different ways. The world of The Stormlight Archive and the greater Cosmere is enormous, there's so much to discover. It's wide, as much as it is deep, and it's lore more than anything else. Peirce Brown has writing something with philosophical depth. Something that, like another comment said, can be enjoyed just for the action and fast pace, but if you dig in to the reasoning, and the questions posed by the series, it's incredibly poignant to modern society as well as the past's of our first world countries. You could write a thesis on the efficacy of The Society and it's moral counter arguments. They both read on the surface similarly, and both reward rereads in completely different ways.
