I'm not entirely sure what you mean by "aggro gain". As for AI choosing targets, they tend to target creatures that have a higher damage potential. This usually means large stacks of lower level units. They seem to have a preference however for certain special units, such as inquisitors. I've found that phantoms or summoned thorns also seem to get preference. Finally, if you have a unit next to an enemy ranged unit, if the ranged unit can move away and still shoot, it will almost always shoot the unit it just moved away from. That can be very useful for figuring out how to neutralize enemy ranged units.
