The Kaminoan stated that the Clones were "...vastly superior to Droids."
The Droids were mindless, they didn't have any logic at all, they relied on numbers because more Droids would be destroyed in a battle.
Palpatine created the CIS, he is in control of everything, he would win either way?!
The Clones were dominant.
