Lol, that's one thing I don't like about Ronaldo as a person, he's a very fantastic player, but he dive so much, the other like him is Neymar, he can fall with a wind blowing around him too... Lol
Messi is more of a determined player than the too of them. Though, all players do it to get advantage over their opponents, but Messi is a bit real than the other two... Lol
