The DOU is better then the sleeper all the way, with the sleeper you have the chance of resyncing your controller in the middle of switching modes,plus when your in a game that can screw you over big time. Also when your charging your controller you can switch modes. The DOU is better because of the tac switches, you can charger your controller and switch modes and easyer to turn on and off, just little things that make it better they both do the same thing though.
