Should I pick Malagor or Morghur as my Beastmen Shaman?

So I was wondering who I should pick. I can get Malagor right now but if I want Morghur I need a Chaos Spawn unit, I recruited a RR Chaos Spawn which I guess doesn't count because I still can't recruit him. So if I want Morghur I need to disband my RR Chaos Spawn and recruit a regular CS unit which means waiting a turn in encampment stance and I don't really like encampment for Beastmen unless I'm trying to hide ( I'm in Stirlands provinces and there's quite a few men armies around me and I don't want them settling in the settlements I just sacked, I'm really just trying to destroy all of the armies and then continue on to their settlements) What do you think I should do? Both Lord's have some good starting traits but I just don't know who to pick.
