Malacath-Trinimac faith is always something influence orcish society greatly, but right now we only have malacath faith.
While both faith require valar and bravery, the malacath one is more "brutish" and more conservative, and Trinimac faith is more about knightly loyalty and more open minded (but they also have fanatics branch, The Vosh Rakh).
We can have a peek of both malacath and trinimac orc society in ESO orsinium dlc: Females have basically no right in malacath orc tribes, and their hierachy is stubborn and fixed, they also have no sympathy for physcial weaklings; Trinimac orcs are more open minded about females getting invloved as major roles, trying make a new united hierachy instead of the traditional many tribes ones, and more about a indivisual's ability (not only physical) rather than one's social statue.
In fact I believe the "old way" is what makes orcs never united (you are powerless if you are female/not of chief bloodline/ physically weak in the malacath way), and second, third and possibly fourth founder of orsinium realize that and thought to use "new way" to truly units orc tribes together to get their own province. It's kinda cut the orc play through to half without the trinimac faith in the mod.
