This thread will be a poll based tournament, narrowing down 48 acclaimed Marvel stories into just three, after which point those three will be pitted against the 3 best DC Stories.

I will post a match up, and you will have 7 days to vote for which story you prefer. It's a structure similar to Wall Crawlers Best Thor Story thread.

Our first match will be

The Eternals Saga (Thor #283-301)

vs.

Ultron Unlimited (Avengers #19-22)
