I'd go with the centigors and minitaurs. I prefer fully themed armies and centigors are the bomb. Moving through terrain with a decent amount of high strength hits plus the possiblilty of frenzy on the right turn. also if you mark them khorne for that extra attack. Minitaurs are also pretty good. Better than an ogre not as good as a troll. Give them Great weapons and watch your opponents cringe. only thing is that the hell cannon is much more simple tactically. Point and shoot. You just have to watch out for crafty players with fast cavalry dragging it along on a leash.
