Whats the best saw contraption?

Me and my sister Sara we're one day talking about random stuff while trying to pull an all night-er. we we're trying to keep each other up. we ventured of into this subject and well we don't know which say contraption is the best. I've seen all the saws but the 3D one that's new. and i have to say its the one where the guy gets chopped in half by the giant ex... they all kinda make me squeamish >.<
