OP, my still work composition does not favor portrait or landscape. I try to do what is best for the image. Although, a lot of my work is candid, from the hip shooting and is sometime more dependent on how I can hold the camera and get a shot off quickly and candidly.
When I look at a bunch of my photos it seems to be more on the landscape end of things. Maybe 75% or more. I used to shoot a lot of square comps back in the film days when I used a Hasselblad SWC, but don't do that much square work now unless it demands it or is fisheye.
When shooting with a circular fisheye it does not matter how I hold the camera...landscape or portrait generally look the same when it is done. In-camera they look different in the review. The circle is smaller in the review when the camera is held in vertical position.
Here is a candid fisheye shot...was about 2 feet away from her!
Here is a candid portrait shot
Here is a candid landscape shot...cropped towards the square-ish end of the spectrum.
When I'm making a book I look at the comp mix and count them up. For book format, if more photos are landscape, that is what I generally go with for the book and vice versa is I have mostly portraits..
