It is like you can say JH and CH only go after armed folk and enjoy the challenge of being on another's territory (apparently the novel (I think) says that CH had the recordings from JH's mask and was motivated by that, so he is intentionally following his style a little) so they are similar but the Superpreds, while enjoying hunting as well, prefer unsporting methods by utilizing more technology and kidnapping game so the preds can have the home field advantage.
The intentions and methods are different too. JH and CH are just enjoying the hunt and challenge, but using slightly different methods, subtly and "one at a time" for JH and more engaging and melee style for CH, while the super preds just want to self improve and make themselves into more efficient killers. They all hunt but there are differences, some subtle and others much more obvious.
