I find that the Technic Packs are general packs, not specilised on one area of MC Mods. But most mods, while achieving the same end goal, have different ways of doing it. Such as IC2, TE and Factorisation. They all have ore processing, but IC2's is fastest, but not that compact, TE is compact but quite slow (but still quite fast) and Factorisations is not compact, slow but can make 3x ores. Different Ways, Same Goal.
