I'm looking to expand my graphic novel collection, so I was wanting some feedback on the quality of various Captain America and Thor collections. Some collect minis but I know others are just a compilation of one shots.

The ones I'm curious about are:

Captain America: Red, White, and Blue
Captain America: Theater of War
Captain America: America First

Astonishing Thor
Thor: Heaven & Earth
Thor: Godstorm
Thor: First Thunder
Thor: Wolves of the North

Also, if you have any suggestions for other relatively obscure Captain America or Thor collections, let me know. I have quite a large collection already, but you might mention something I've forgotten about or never heard of. Thanks in advance!
