They literally sit around in COTE talking smack to each other about power levels and who's stronger than who else. It's like how Food Wars is a battle manga at it's heart but about characters doing battle through cooking food. COTE is a battle manga at it's heart but about characters doing battle through intelligence and schemes. That's also what Death Note is.
Yeah, that's why I made the comparison between this and Death Note. Because I kinda see what you're getting at. But I'm anime only and have only seen the first season. The stalker thing, getting a dude to study, and that ridiculous pool episode all felt hella side-tracked. As the season went on and Class C really felt more like antagonists, I can see what you mean. The last couple of arcs definitely felt more like Death Note. But it didn't always feel like a battle manga/anime with some of those other subplots that carried across episodes.
