I use Linder, Lighthouse and Supersafe stock books. So far the Supersafe is the LEAST liked of the three brands.
My Supersafe is a normal hard bound book style. Very rigid binding on the pages. As you add more and more stamps you get a 'fat side' effect the same as if you stuffed your stamps in any hard cover book.
Linder and Lighthouse use a more flexible binding. Linder has a 1/2" flex joint and Lighthouse is about 5/8". This way adding stamps does not cause the right side to flare out an inch wider than the binding.
I have both white and black page books. Both work fine for me as I do not scan from the book. I use other holders when scanning.
Also, you can use stock books for souvenir sheets by placing them in the lowest slot one per page.
An alternative for temporary storage would be a simple school binder. Buy some manilla and plastic pocket stock sheets as needed. I use manilla for temp storage of used stamps and a few mint. I use the plastic pocket type for holding more valuable stock especially mint. The plastic pocket can be purchased in a wide variety of formats such as one pocket for souvenir sheets.
