Universal has Hulk, Dueling Dragons, soon to be Dragon Challenge (which does count as 2 as the track layouts are not identical), Flying Unicorn, Pteradon Flyers (which is technically a coaster), Mummy, Hollywood Rip Ride Rockit, and Woody Woodpecker.
WDW has Space Mountain (which only counts as one since the tracks are mirror images of one another), Big Thunder Mountain, Goofy's Barnstormer, Rock 'n Rollercoaster, Expedition Everest and Primeval Whirl (which also only counts as one since the tracks are mirrored identical layouts).
So if my math is right, Universal has eight coasters, WDW has six.
