Hi Rob,
I have both libraries, and they're definitely different. If you had to summarize them, I'd say that SOV is more classical in nature, including soloist lines and some evolving sounds like ooh-ahh etc. Voices of the Apocalypse is more cinematic-sounding, like those dark choirs you hear in thrillers or action movies - very Carmina Burana-like. It also has key-switchable vowel sounds as well as single consonant sounds, so you can sort of create "words" or phrases. They do have some choral pad-type sounds (lik eooooh or eeeeh or mmmmmm) but those don't sound as legit or as realistic as the SOV choirs that do the same thing. If you're familiar with the composer E.S. Posthumous (they use a lot of his stuff in movie trailers), the stuff he writes sounds like VOTA, although I think he uses a real choir.
Ultimately, they're both strong if used the same way you use the VSL -- if you combine different sounds or "articulations" vs. just playing them straight-up, they'll sound much more realistic.
