Hector vs. Harken:
Hector is second best unit early on and has basically top tier performance until other people start promoting, at which point his position he declines quite a bit. Harken probably joins too late to do all that much in Pale Flower of Darkness, but then he wins for three chapters until Hector promotes. The Berserker only has 1 empty slot, Harken's likely not coming to that. 3-2, Harken's favor. Then we've got 4 "real" chapters left in the game if we go to 32x, though spots are a bit limited there so Harken might not get to go. But even if Harken wins all the remaining chapters, which is arguble, Hector by that point is a more than competent combat unit himself and he had all that early game epic win and mid game lesser utility, so I'd see him winning overall fairly easily. Hector to Bottom of High, Harken to top of Upper-Middle?
