DanMachi is mostly about Bell working to become better because of his admiration for someone Ais, and about his adventures on the way to his goal. If you love adventures, anime which would motivate you, or simply fantasy, this anime might be a good choice for you. I liked the world, some of its details, however you won't get too many details as in for example "Mushoku tensei". What I liked the most is Bell's perseverance and the risks he took to get closer to his goal of becoming better, something I could relate to myself.
P.S. Some complain about the ecchi elements in this anime... maybe it's just me ignoring them, but I didn't see too many of them.
