Video editing and compositing are the main things. These don’t seem to specialize in those tasks, while Adobe offers too many features and has too many quality 3rd party plugins to really be replaced. Even if there were programs that could compete, learning how to do things you know how to do in another program is a pain in the ass. The way programs work together is also a key thing Adobe can offer because they own multiple programs. Ideally there would be common standards to allow programs from different teams to work together just as well, but I’ve yet to see it.
