Well, at least, chunin exams are technically legal, while coliseum seemingly wasn't. Also, the coliseum shinobi were rather taken captive and thus had to fight each other unwillingly, while chunin exams are an event where the participation is voluntary. At last, chunin exams' participants aren't that powerful and skilled shinobi, they are just genin after all.
