I wrote a long reply extolling the virtues of both Trinity and Aberrant, but the server ate it. I now present the shortened answer:
Aberrant: Worldwide Phase 1+2 for metaplot and adventures. Teragen is great. Utopia, Directive, Elites are good if doing specific plots or using them. Aberrants is awfully weak. ReignofFear.com+XWF+Fear and Loathing were kinda useless to me.
Trinity: World+Order books. I liked them all (and used them all). Extra bonus for Stellar Frontiers. Field Reports are lotsa flavour, but make sure you get 'em cheap. Remember to get the final one here:
http://homepage.mac.com/bbaugh/asas/Asia_Ascendant.pdf for free. Bruce Baugh was allowed to release the material for free after White Wolf cancelled the line, to get it "out there for fans". Darkness Rising + Alien Encounters are great adventures and the last series has metaplot and metaplot, but then that is part of what made Trinity great.
