Whats the Greatest comic you've read?

The question is quite simple in your opinion, what is the greatest comic you've ever read. Not the most expensive, or the most well known. Its all a matter of opinion, so let it begin!

I'm on my phone so can't really look it up, but by far the greatest single comic that comes to mind was somewhere around 131 of Ultimate Spiderman. The issue that was nothing but Jameson writing Spiderman eulogy, followed very closely by the previous issue with no dialogue.

Only comic that I can think of that I had to keep stopping reading to keep from bawling.

For series probably far and away The Walking Dead, if not Injustice.

In Green Lantern vol. 3, #180 Kyle Rayner believes that Major Force has killed his mother and his powers go completely ape shit. They do this big battle in space with an ending that I will always remember. Check it Out.. its not a big moment in the green lantern history but one of my favorite for the character.
