I would say these both have a similar art style first of all. Same kind of vibes overall can be felt from both too. Both are good anime.

Psycho-Pass

Psycho-Pass and Ergo Proxy share genres. To name a few: Sci-Fi, Seinen, and Psychological. Psycho-Pass for me also exuded a dark mood. If you're looking for an even darker atmosphere then Ergo Proxy is for you. Not to mention, Ergo Proxy is one of my favorite animes :) Definitely give it a watch, I highly recommend.
