Five vs three? Easy the five, each of them is individually powerful and they have a lot of sorcery- numbers means you can have someone as great as Muur stand back and focus *exclusively* on sorcery while saber badasses like Ajunta handle the melee end.
Two can tangle with Anakin, while the other three go 3v2 on Exar and Dooku, which goes badly for the two. Dooku's likely the first to fall.
