i usualy do both, mostly double clutch into 3rd and use engine and breaks to slow it till its close to idle then i put in clutch or take it out of gear. My dad told me when you are engine breaking you are getting as good or better gas milage as idle. Also the only time i dont engine break is in snowy weather because it can lock the tires up and thats not good.
