In short, the difference is that they are not part of the same order. The Templars, in particular, are not explicitly a branch of the Zakarum faith as Crusaders and Paladins are.
The Templars are based out of Westmarch and a relatively new group compared to the Crusaders. I recommend speaking with Kormac throughout each Act as he'll eagerly tell you about his order. In
Reaper of Souls, he'll have even more to share as he delves into his suspicions that all is not as well with his brothers and the Grand Maester.
Crusaders and Paladins, on the other hand, are different branches of warriors of the Zakarum faith, originating in Kehjistan, the largest of which came from Travincal. There's a
ton of history behind them both, and we may possibly be working on some things to share soon that go even more in depth, so do keep an eye out on our upcoming blogs. ;)
