Well since all my other favorites have been mentioned, I'm just gonna say MD Geist 1. Not a hint of irony in my enjoyment whatsoever, sometimes all a man needs is about an hour of badass shit to get through the day. The vocal tracks are sick and while the animation isn't the best, the designs for the power armor are cool and the fights are least choreographed well enough. Geist's an interesting protagonist in that he's just a complete psycho with no nuance or anything, he just wants to kill people and the story knows that. MD Geist 2 however isn't very good, just a complete downgrade in every way despite having higher stakes than the first one with the Death Force going around. The only good part of it was Krauser's death because it was really funny.

Although in another direction, it'd be Kowarekake no Orgel. Nothing like a show that makes you wanna curl up in a ball and die when it's over, you know? It just does everything right to make the ending hit you in the gut in the best possible way.

Definitely. I watching this multiple times per year along with a few other OVAs ( Area 88, Grey: Digital Target and Dallos).
