I have never owned any of the channa species, but from the stories that I have heard, there are some subtle differences between channas and cichlas. The cichlas only eat prey that they can fit in their gaping mouths. Whereas channas, as I am to understand them, can be very vicious and will tear larger pieces of prey into smaller chunks. Both are awesome predators and I agree that cichla lack some of the "personality" that a lot of larger cichlids have and that channa species appear to have as well. Instead, cichlas tend to be more like anxious puppy dogs, always waiting to play catch or wagging their tails wildly. It is this energy that I love about my pbass. It pumps me up everytime I see them.
