The choice is between the Winterax and Amani trolls. To give you some backstory:
The Winterax somehow split off from the normal Drakkari and went to Alterac, where they fought both the Horde and the Alliance. They were lead by Korrak, who is so chad that he’s come back from the dead multiple times. He was last seen in the Amphetheater of Anguish, kicking [redacted].
The Amani trolls are quite badass. They fended off the Elves and pretty much all the Human kingdoms for a very long time, and almost didn’t lose to the Alliance and Horde’s greatest heroes. Lead by Zul’jin. I believe Zul’jin skinned Lor’themar alive one time. That’s got to count for something, right?
Debate!
