Lelouch never Geassed his followers. His tactics, leadership, and sheer charisma are all his own, and that's what makes him dangerous. That's not to say that the Geass isn't his best weapon though, but it's not all he has going for him.
The support from Kyoto he had to really earn himself, or did you forget that face to face meeting with the boss there, whom he didn't Geass. Kaguya DID push for him but she can't make an arbitrary decision in the way Euphemia could.
Suzaku is good at piloting Knightmares, and he gets a really nice one to ride around in. Those are the only merits he earned on his own, everything else was handed to him.
Lelouch got Geass. That's it.
