I've been alternating over the past couple month between the Simonson "Thor" and "Tomb of Dracula" v1.
I'm on the tail end of "Thor" and would easily regard it in the top handful of omnibus books. The last half has felt like a long-running coda of sorts to the major events that occurred in the first half of the book. Just when I thought that it was hitting a lull, it hit me with the Executioner's big moment and I was just floored.
In "Tomb of Dracula," I'm just getting to the Dr. Sun issue(s) that I've seen referenced as being some of the best of the series. Issues throughout the teens hinted at a big nemesis emerging and I'm hoping that Dr. Sun ends up being a compelling antagonist.
