Not really in Another World With My Smartphone has a bland main protagonist who uses a smartphone to solve his problems but he’s also really overpowered, has photographic memory and literally ends up marrying every female character who joins up with him. Also he travelled to that world via reincarnation after God killed him by accident rather than being magically transported and he’s okay with leaving his old life behind. Also the animation is better (not a easy hurdle to clear in this case) and the world building is better. Also unlike Master of Ragnarok’s protagonist who constantly puts himself down when he does something, Smartphone’s protagonist humbly accepts credit and is aware of his capabilities. I can understand confusing Master of Ragnarok and In Another World With My Smartphone as both are regarded as trash Isekai anime with similar premises but Smartphone is the better one of the two
