A quick review for people who have finished the anime (no spoilers)
Noragami - it feels like each chapter has something important to tell and spice up the plot. It has a lot of mysteries and plot twists which make you read more and more. A lot of characters can grow on you and they become likeable.
That said, it is a well-thought-out story as well as world-building. It feels like the author has thought of every single possible situation.
The adaptation itself is quite strange. They rearranged a whole lot of scenes, but I also have to say that I very much prefer anime's order to manga's. However, I must say that the last arc of Season 2 is way different from the manga's so I suggest reading it either from the start or from chapter 35.
I would definitely recommend Noragami to anyone, especially for those who have finished the anime, just for how good it is.
