EIS and Ajin have similar dark and offensive themes with a main character that gains a crazy amount of strength although EIS is more of a power fantasy with no power creep. Ajin takes more of the struggle as a result of MC's sudden climb to power and that's what made me enjoy Ajin a lot more in comparison. If you don't like CGI anime then Ajin might not be for you.
