I waited a LONG time to build my Menace Class because of the restrictions to the Voodoo Schools it presents. My two favorite schools are Illusion (For Ghost and Witch) and Communion (for Saviour and Slave outfits). However, I can't get these schools together. I feel Illusion is strongest of all, but it only pairs with Destruction and Excess. The Destructor suit sounds awesome but I've never used it, and I kinda really don't like Darkones, nor Demonic Rituals etc, for both a flavor stance and a playability. So my only other option is the Illusion/Excess pair. Excess seems kinda weak, but I'm interested in seeing out the Fairy Outfit works. So I have a Fuego built, but not crewed. Overall, I think this is hardest part of the game, and I'd give my eye teeth to be able to get a codex of Communion.
Paralyzed by choices, eh?
Anyway, I think it's not much of an choice in the end, as illusion is wastly superior to communion and fortuna is somwhat better than fuego as it can go to space.
