The sham/monk duo will probably come on top in the long run (imo), but still it's going to take a while until it takes off. The fact that it will be your first chars here, and both being Iksars will limit your vendor/banking options so to speak. Also, melee are a lot more gear dependent than the mage/necro combo.

Then again, you already know these things, so it's really upto you, and what you want to accomplish. Will you level slowly and take your time, or you want to blow through levels asap? Are you going to look into heavy raiding as well?

Still, if I were you, I'd take some time and think about the de cleric / de enchanter duo too. It might struggle a bit early/mid levels, but after a while it just turbo-boosts into stardome.
