They both share the same characters; you can literally match the characters from both sides. The plot is also the same; humanity is on a brink of extinction because of a source they know very little about and now humanity is fighting back. If you liked Owari no Seraph you will love Shingeki no Kyojin!

This is an obvious comparison, but not for the reasons most people belive... The thing most similiar thing about them is their pace. In every epiosde there is something happening, there is a lot of action (both mental and physical) and the dialogues are very fast; because of that, not a second is wasted. The tension between two opposing factions is almost continouslly present which builds the dynamic even further. After you have finished an episode, the next one demands to be watched. The second thing very similiar is the main character's usage of other people as his pawns as a mean to victory/salvation and the main character's vision of creating a better world or an utopia for worthy people. Both series quoestions what is right and what is wrong and if the end justifies the means, as well as other controversial topics like - should all human lifes be measured equally. If you liked Code Geass, you will probably like Death Note, but maybe not vica-versa, because the atmosphere in the two is different. While Death Note has a lot darker and gothic feel to it while Code Geass' athmoshepre is more revolutionary and, well, more colorful to say at least. (I avoided watching Code Geass because of the art style and the mech genre, but later when I decided to give it a shot I realised the charm of the anime and it quickly became one of my favorites.)
