There are 2 anime I'd recommend. 2 anime that I really enjoyed and consider top tier, but are no where near as popular as they deserve to be.
First, Shoukoku no Altair (or Altair: A Record of Battles). It's a solid story with a lot of clever strategy, comparable to Code Geass. The main character might come off like a Mary Sue but I find him quite compelling.
The second is Bungo Stray Dogs. I see it as a very good mix of basic shounen and some seinin. Each season gets progressively better. There are some kick add fights, really sweet animation, it's very funny, has a really likable cast of characters, and has some good mystery sub plots and other interesting plot threads that would almost make you feel like you're watching Dark Knight or The Winter Soldier.
