It's a vague question but in general, no, I don't find Africans boring in comparison to South/Central Americans. In fact I think the behavior of African cichlid is a bit more variable than the behaviors of SA/CA cichlids but I do very much enjoy both.
I'm still fascinated by the complex social structures of Malawi Mbuna. How their hierarchy works, who's where...it changes frequently. They're highly social animals. Most people don't bother to dig past the part where "they're pretty to look at" and mistake their constant activity for mindless movement. People knock them cause they're mouthbrooders and don't display any parental care but that's not the whole truth. A female mbuna can display very tender care and consideration for her fry. I've seen them take fry back into their mouths when they were already too big to fit more than a few in, hide their fry in small rock rubble because they're obviously safer there than in the pile of bigger rocks where bigger fish can fit through, even chew up and spit food for the little ones to eat. They can be very calculated and intentional.
The colony building behavior of other African cichlids is also quite fascinating, like those of Neolamprologus brichardi, and Neolamprologus pulcher. Two very similar cichlids, both colony-building only one species allows inactive males to stay within it's colony and the other chases away it's young males upon reaching sexual maturity. Both are rapid producers of fry and both make excellent parents and have the heart to challenge fish much larger than themselves to protect their colony.
So no, I find all groups of cichlids fascinating in their own way.
