In all of my games, Alexander expands slow as molasses, techs hella slow, and gets vassal'ed pretty fast. Never seen him beat anyone.
I've had the same experience with Alex. Genghis can get going but he usually techs pretty poorly in my experience.
I go with the majority, Shaka is the most dangerous. For some reason, he doesn't tech as poorly as the other Aggressive leaders and seems to make better decisions regarding who to attack.
Could it be that most Aggressive Leaders will build plenty of Barracks, while Shaka's Barracks (the Ikhanda) directly reduces his City Maintenance costs and thus indirectly increases his tech rate?Shaka is the most dangerous.

What I have experienced is that Suruavaman seems to be the runaway guy in every game I have played he within, second strongest AI is Mehmed I think, they both expand really fast and usually grow to be the strongest. But for aggressive leaders I think Montezuma is the most dangerous one.
I seem to get Zara Yaqob on almost every map I play, and he always goes completely nuts and settles half the map. He's not super aggressive most of the time, but he's incredibly expansionist and eventually when he's got rifles on his enemies swordsmen he's going to stop playing nice.
One thing I frequently see is Zara settling so many cities the generator runs out of names and just calls them barbarian city names.
I never knew Zara was such a powerhouse. I am playing as Zara in my current game. (I use random civ starts.) I have never played as him before and only had him as an AI once before. As you all mention, I am walking all over all of the AIs in production, expansion, culture, income, and expansion.
That's been my experience with Zara as well. He has two very good traits. His UB doesn't suit me but his UU is very good. He's one of the few leaders who I make it a priority to get gunpowder with. I don't know if it's a good idea or not, but I usually upgrade my Oromos instead of building new riflemen or infantry if I can help it. I'm a sucker for two promotions free. Drill I and II aren't great, but now Drill IV is there for the taking.
