Jack Kirby's use of 4 panel grid

I find comics fascinating, not only in their content but also in the way that content is communicated. With this and subsequent posts I'd like to look at some of the more popular forms of panel arrangements in comics.
Besides the splash page (which is technically not a comic page in the true definition of comics being a medium of sequential panels) the most basic of the common page divisions is the 4 panel grid.
When I think of the 4 panel grid I think of Kirby's Silver and Copper age work on titles like the Fantastic Four and the New Gods, in fact I have a hard time thinking of any other artist that does use this form of page layout.

The 4 panel grid can be good when you have a very wordy page. The sameness of the panels creates a rhythm that is easier to follow. A 9 panel grid might work as well or better depending on the page.
