Lore-wise, what's the difference between Braum and Taric

With the Taric rework coming, and his lore being fleshed out, I think he seems very similiar to Braum. They're both altruistic supernatural beings who protects the weak and defenseless. Don't get me wrong, their visual designs are great and distinct, but when it comes to their personal goals and behaviour, it's difficult to tell them apart. They both save people. Sure there are other good guys like
and
. But Garen's top priority is protecting Demacia and Bard saves people in his own strange bizarre way. Sorry if I wrote badly, english is not my native language.
But there might have been something I've missed. So I'm wondering what makes them different from eachother lore-wise besides appearance and geography
