My impression of how this has been throughout literature is that literature used to be more focused on description until it shifted toward an action-focus in the past century.  As a result, I feel that writers like Lewis and Tolkien that were caught in between the focus-shift are good at balancing both.
I tend to write more action in my stories, but I try to work in some more description to try to balance myself out.  I think that the best track is one that picks some route of moderation between the two of them, but I don't think I can really describe what that route looks like, since writing is more of an art than a science.
