Big Blue and Steiner are at opposite ends of the spectrum. Which one works for you depends on priorities.
Big Blue
* Large one volume ("Big Blue"), but compact. Did I say compact?

Huge advantage compared to the Steiner for WW classical collectors.
* 35,000 spaces, but still a "representational" album. An album with all the possible spaces needed for 1840-1940 would have 80-90,000 spaces.
* As Big Blue began life as a "Junior" album, the spaces are quite simplified: Watermarking and perforation variations are "ignored".
Either a feature or a flaw depending on one's point of view.
* Despite the shortcomings, filling the album (35,000 spaces!) is a huge challenge for most collectors. But, since many of the expensive classic stamps have been left out, it is do-able.

* Did I mention, considering it covers the world 1840-1940, it is compact?

Steiner ( WW classic pages)
* Spaces for
all the Scott major numbers- some 80-90,000, plus coverage of the British Commonwealth until 1952. Watermarking and perforation major number variations all have spaces. But, for me, it will require some 50 1 1/2" Avery binders to house all the pages.

* I'm probably not going to be filling the 1847 "Post office" Mauritius stamp spaces any time soon.

In other words, the Steiner will always have many empty spaces. When one looks at a page, does one see the stamps there, or the empty spaces? How does that make one feel? All good questions.

To reiterate, Big Blue and Steiner are at opposite ends of the spectrum for WW classical collectors. Which one works for you depends on priorities.
