What is the best liquor to get drunk?

My parents are out for a bit and they have this stored 'seceretly' above the fridge: Scotch Wiskkey, Canadian Wiskey, Rum and White Rum. I want to get like feeling better and not depressed but not like obvious drunk, and I would like to do it with as little gone missing as possible. I know zippo about liquer and my brother would tattle if I asked him so help? Oh and no lectures please, I've been through more effing sh*t than most adults.
