Both shows from SHAFT and with the same art style, which I personally completely love. Araragi and Raku have quite similar personalities, always helping everyone, which gets them quite a noticeable harem. These shows also have really interesting and enjoyable characters.

Log Horizon

MMORPG goes wrong, traps all the players inside the game and let them find everything on their own. Log Horizon is far more easygoing and more about living in the game, SAO is darker and definitely less stable plotwise. Oh, and both main characters are looked upon as kind of villains, too, despite not really being one.

Set mostly in school, both are great comedies, with a lot of characters. They are both crazy, each in its own way.

Code Geass: Hangyaku no Lelouch

The most obvious recommendation of them all. Both have main character with superpower with some important flaws. Light and Lelouch have similar personalities, they both want to accomplish their ultimate goal no matter the cost, but Light is more radical. Death note´s quality drops in the second half, which is a shame and a reason why i enjoyed Code Geass more, but they are both worth the watch.

Solving mysteries in both, although Hyouka doesn´t have any supernatural characters. The style of both shows is also similar, with big changes in the personalities of main characters (mostly Kyon and Houtarou, they are basically the same). I greatly recommend both.
